High frequency dynamics modulated by collective magnetization reversal in artificial spin ice
Matthias B. Jungfleisch, Joseph Sklenar, Junjia Ding +5
Spin-torque ferromagnetic resonance (ST-FMR) arises in heavy metal/ferromagnet heterostructures when an alternating charge current is passed through the bilayer stack. The methodol…
Magnetic vortex nucleation/annihilation in artificial-ferrimagnet microdisks
Pavel N. Lapa, Junjia Ding, Charudatta Phatak +4
The topological nature of magnetic-vortex state gives rise to peculiar magnetization reversal observed in magnetic microdisks. Interestingly, magnetostatic and exchange energies wh…
Detection and quantification of inverse spin Hall effect from spin pumping in permalloy/normal metal bilayers
O. Mosendz, V. Vlaminck, J. E. Pearson +4
Spin pumping is a mechanism that generates spin currents from ferromagnetic resonance (FMR) over macroscopic interfacial areas, thereby enabling sensitive detection of the inverse…
