Ultrafast demagnetization of 2d ferromagnets — •Nele Stetzuhn1,2, Felix Steinbach1, Martin Borchert1, Abhijeet Kumar2, Denis Jagodkin2, Clemens von Korff Schmising1, Stefan Eisebitt1, and Kirill Bolotin21Max-Born-Institut, Max-Born-Straße 2 A, 12489 Berlin — 2Fachbereich Physik der Freien Universität Berlin, Arnimallee 14, 14195 Berlin

Two-dimensional ferromagnets are one of the latest additions to the family of 2d materials and offer a new platform to study ultrafast magnetic phenomena. When combining 2d ferromagnets with other 2d materials such as transition metal dicalchogenides (TMDs), the absence of lattice mismatch between layers also makes the resulting heterostructures promising for high-performance spintronic devices. Here, we measure the ultrafast demagnetization of 2d ferromagnets with the structure FexGeTe2 (x = 3, 5) after excitation by a pump laser using time-resolved MOKE. The usually low Curie temperature of FexGeTe2 (x = 3, 5) can be increased above room temperature, e.g. by doping with Ni, allowing us to do element-resolved demagnetization measurements at the free-electron laser facility FERMI. This can give insight into effects such as optical inter-site spin transfer (OISTR) in the material.
