After lunch, a lab tour combined with a scavenger hunt took place. The main goal of this activity was to show the equipment and the labs such that participants can get an idea of the work that is performed in each lab. The activity included an introduction into the work that is conducted in the lab and within the research group. Furthermore, in each lab a riddle, puzzle or experiment had to be solved to get a clue. After all the labs were visited, the sum of the clues led to a final destination.
The event concluded with a poster session where the PhD researchers showed off their work. This part of the workshop was open to the general public as well. In this activity, the PhD researchers had the chance to defend and discuss their work with scientific colleagues from the different research centers in San Sebastian.
An international committee including leading researchers in the field was selected to assess the research project:
- Dr. Hans Huebl (Technische Universitat Munchen).
- Dr. F. Sebastian Bergeret (University of the Basque Country UPV/EHU).
- Dra. Arantxa Fraile Rodríguez (University of Barcelona).
After the defense, we asked Dr. Juan Manuel Gomez to explain us a bit more about his project:
Which was the subject of your thesis?
My thesis belongs to the field of spintronics, which is a promising field to overcome the problems of the current electronics, by exploiting not only the charge but also the other degree of freedom of an electron, the spin. In particular, my thesis is focused on different spin-dependent phenomena in magnetic insulators / heavy metal interfaces and how they affect the creation and transport of spin information through magnetic insulators.
Why did you choose this subject?
I discovered spintronics in a course during my master’s degree. I felt really attracted to this field related to developing new technology based on new physical effects. Then, I decided that, if I had the choice, I wanted to do my PhD in spintronics. I knew that in nanoGUNE there was a good group working on spintronics and there was an open position at that time. I am glad that I was chosen for the PhD position.
Which metodology/techniques did you use?
During my Ph.D. I had access to different deposition and characterization techniques. We use bare magnetic insulator substrates on which we perform metal deposition, lithography processes, and all the magnetotransport measurements.
Which have been the main conclusions?
My thesis had two different parts, in the first one, we probed the spin Hall magnetoresistance (the change of the resistance under presence of an external magnetic field) as a powerful technique to characterize the magnetic and conductance properties at the interface. This technique can be useful to optimize the conductance at the interface that is important for writing or reading processes in magnetic memories. The second part of my thesis is based on the transport of spin information via magnons (or spin waves) through a magnetic insulator which allows for the spin information to be transported and detected over long distances.
Using magnons allows for transport of spin information over long distances in comparison to other spin transport mechanisms. Secondly, the fact of using magnetic insulators prevents the emergence of spurious effects related to the charge flow which normally arise in conductors and unnecessary energy losses. Both of these points make this kind of materials very attractive for future spintronic applications.
How do you feel now that you have finished the thesis? Which are your plans for the future?
My first feelings were relief and happy. I am relieved after finishing my PhD because the last months were a bit tough, but I also feel really happy because in the end, all the effort was worth it, and, in my opinion, we have finished a beautiful thesis with many interesting results. About my future, I have a contract with nanoGUNE for one more year, and after that, I would like to continue in academia so I will probably go abroad for a postdoc.
The beauty, gastronomy and cultural life of San Sebastian are some of the most outstanding assets of our small city. Nevertheless, following the last virtual issue in ACS nano, San Sebastian also stands as a city of science and technology, specially devoted to the nanoscience field. The present work highlights the contribution of the nanoscience community of San Sebastian to nanoscience and technology.
As described in the editorial of this issue, some of the main representatives of the nanoscience community in San Sebastian stand together, namely, the Nanoscience Cooperative Research Center (CIC nanoGUNE), the Donostia International Physics Center (DIPC), the Basque Center for Macromolecular Design and Engineering (Polymat), the Center for Cooperative Research in Biomaterials (CIC biomaGUNE), the Technology Centers Cidetec, CEIT, and Tecnalia, and the Health Institute Biodonostia along with the Centro de Física de Materiales (CFM), a joint initiative of the University of the Basque Country (UPV/EHU) and Consejo Superior de Investigaciones Científicas (CSIC).
This research force has contributed considerably to ACS Nano with more than 100 publications during the past decade, some of which have already had significant impact and are highlighted in this virtual issue.
As reported by the authors “This collaborative work has been combined with our commitment toward industrial development of nanotechnology both locally and worldwide, which has led not only to an increase in top-notch industrial research in our community but also to the launch of a number of promising nanotechnology-based start-up companies”.
The entities highlighted above, express they are confident that, with the continuous and synergetic support from Spanish and Basque authorities, the research activity in the area of nanoscience and nanotechnology will continue to flourish in our beautiful city.
This thesis explores the Hall spin effect, an effect that takes place in metals with spin-orbit coupling and allows charge currents to be converted into spin currents and vice versa. These conversions are of huge technological interest as they have the potential for use in the process to write magnetic memories (like MRAMs) and to read them (as in spin-based log circuits, a recent proposal by Intel). This research has revealed the mechanisms that contribute towards this effect in certain metals, such as platinum (Pt) or tantalum (Ta), which has made it possible to show how the efficiency of this conversion can be enhanced. Platinum (Pt) has also been combined with graphene to produce a device that can efficiently convert spin currents into charge ones.
The Hall spin effect is related to the anomalous Hall effect, known since the 19th century but little understood until recently. The second part of the thesis shows that this relationship in ferromagnetic materials is more complex than previously thought.
Edurne Sagasta studied physics at the UPV/EHU-University of the Basque Country and after getting a Master’s degree in Nanoscience and Advanced Materials at the same university, she started her PhD thesis at nanoGUNE. ”After studying Physics at university, I wanted to do something that would be more practical. At the same time, I wanted to get involved in a project with more people and have the chance to visit different labs across the world; in short, to embark on a research project,” said the researcher. "Once I had finished my PhD, I decided to make the leap to the world of industry, and right now I am working for the company Mondragon Assembly,” she said.
