Tunable Enhancement of Magnetization Dynamics by Crystal Cut at Interface Exchange Coupled $\alpha$-Fe${}_2$O${}_3$/NiFe Heterostructures

Hassan Al-Hamdo, Tobias Wagner, Philipp Schwenke +8

We investigate spin dynamics in $\alpha$-Fe${}_2$O${}_3$/Ni${}_{80}$Fe${}_{20}$ (Py) heterostructures, uncovering a robust mechanism for in-situ modulation of ferromagnetic resonance (FMR)…
