Coherent ac spin current transmission across an antiferromagnetic CoO insulator

Coherent ac spin current transmission across an antiferromagnetic CoO insulator

The mechanism underpinning the frequency mismatch between THz magnons and the GHz spin currents observed in antiferromagnetic insulators remains unknown. Here, the authors demonstrate that, in a Py/Ag/CoO/Ag/Fe75Co25/MgO(001) heterostructure, a GHz spin current transmits coherently across the antife...
