New process for YIG structures on arbitrary substrates
TRR227 projects of G. Schmidt (B02) and G. Woltersdorf (B01 & B02) published their latest results on the integration and characterization of YIG structures on arbitrary substrates in the AIP journal Applied Physics Letters. The paper was selected as featured article and recently highlighted on the front cover of the Vol. 117, Issue 23, 07 December 2020.

In their paper, the authors present a process that allows the transfer of monocrystalline yttrium-iron-garnet microstructures onto virtually any kind of substrate. Using time-resolved scanning Kerr microscopy and inductively measured ferromagnetic resonance, they can demonstrate that the structures retain their excellent magnetic quality. In the future, this approach will allow for types of spin dynamics experiments until now unthinkable.
