You recently published 3 papers simultaneously in 2 prominent journals. What are they about?
We have actually analyzed how magnetism can be controlled at the user interface in between ultra-thin cobalt and organic molecules. In one research study (Science Advances), we found a specific, up until now undiscovered magnetic layer at this user interface, which we had the ability to expose using ultrafast laser pulses. In another research study (Nature Communications), we had the ability to reveal that molecules transform cobalt’s classic magnetic structure entirely and develop a novel “glassy” phase. Lastly, we showed (Nature Communications) that targeted optical excitation can change magnetism at the interface within trillionths of a 2nd.
What was the goal of the EU job INTERFAST, within which you conducted your research?
INTERFAST ran from May 2021 to October 2024. The objective was to produce entirely new possibilities for managing magnetism in a quickly, targeted and energy-efficient method. The technique was to combine metals with organic particles and utilize the unique interactions that happen precisely at the interface. In this way, it was possible to change product homes “at the push of a button”, so to speak, an amazing basis for ultrafast and energy-efficient computer innovations in the future.
You collaborated with partners from numerous countries. What shape did that cooperation take and what were the advantages?
We were a global team with partners throughout Europe, who each contributed their own specific knowledge, ranging from the production of materials and modern measuring methods to theoretical modeling. We fulfilled frequently online, visited each other’s labs and performed experiments together. The main advantage was that we were able to approach problems from different angles, validate results rapidly and utilize equipment that would not have been offered in one lab alone.
About the scientists
Mirko Cinchetti is Teacher for Experimental Physics and head of the Cinchetti Group– Excitations in Functional Quantum Materialsat TU Dortmund University. In his research study, he examines how light can be used to control fundamental excitations at surface areas and user interfaces, such as in quantum products, in an extremely brief time. His main interests are spintronics, ultrafast characteristics and the advancement of brand-new principles for future quantum technologies.
