Revolutionizing cloud storage
TRR227 physicists together with colleagues from Konstanz, Prague and Uppsala investigate magnetization dynamics of rare-earth metals for potential application in ultrafast data storage.
News from Sep 24, 2020
A recent contribution to the fundamental understanding of the magnetization dynamics of materials with strong magnetic anisotropy has been published in the journal "Science Advances". TRR227 scientist Martin Weinelt (A01) and a team of international colleagues employed time-resolved photoemission spectroscopy and orbital-resolved spin dynamics simulations to shed light on the demagnetization dynamics in rare-earth metals Gd versus Tb, where ultrafast magnon generation plays a crucial role.
