You just recently released three papers at once in two prominent journals. What are they about?
We have actually taken a look at how magnetism can be controlled at the interface in between ultra-thin cobalt and natural particles. In one research study (Science Advances), we discovered a particular, up until now undetected magnetic layer at this user interface, which we had the ability to reveal using ultrafast laser pulses. In another study (Nature Communications), we were able to show that molecules transform cobalt’s timeless magnetic structure entirely and produce an unique “glassy” stage. Finally, we demonstrated (Nature Communications) that targeted optical excitation can modify magnetism at the user interface within trillionths of a 2nd.
What was the goal of the EU project INTERFAST, within which you performed your research?
INTERFAST ranged from May 2021 to October 2024. The objective was to produce totally brand-new possibilities for managing magnetism in a quickly, targeted and energy-efficient way. The trick was to combine metals with natural particles and utilize the unique interactions that take place specifically at the interface. In this method, it was possible to alter product properties “at the push of a button”, so to speak, an interesting basis for ultrafast and energy-efficient computer system innovations in the future.
You collaborated with partners from a number of nations. What shape did that cooperation take and what were the advantages?
We were a global group with partners throughout Europe, who each contributed their own particular know-how, ranging from the production of materials and advanced measuring techniques to theoretical modeling. We satisfied routinely online, went to each other’s labs and performed experiments together. The main benefit was that we were able to approach issues from numerous angles, confirm outcomes rapidly and utilize equipment that would not have actually been offered in one laboratory alone.
About the researchers
Mirko Cinchetti is Professor for Experimental Physics and head of the Cinchetti Group– Excitations in Practical Quantum Materialsat TU Dortmund University. In his research, he investigates how light can be used to control fundamental excitations at surface areas and user interfaces, such as in quantum materials, in a very short time. His primary interests are spintronics, ultrafast dynamics and the advancement of new concepts for future quantum technologies.
Dr. Mattia Benini is a postdoctoral scientist in the Cinchetti Groupat TU Dortmund University. His proving ground on the time-resolved magneto-optics of hybrid user interfaces between metals and particles. His main interest is the experimental research study of ultrafast magnetic processes that allow new techniques for spintronic applications.
