Coupled skyrmion breathing modes in synthetic ferri- and antiferromagnets

Martin Lonsky, Axel Hoffmann

We present micromagnetic simulations of the dynamic GHz-range resonance modes of skyrmions excited by either out-of-plane ac magnetic fields or spin torques in prototypical synthet…

Spin Seebeck devices using local on-chip heating

Stephen M. Wu, Frank Y. Fradin, Jason Hoffman +2

A micro-patterned spin Seebeck device is fabricated using an on-chip heater. Current is driven through a Au heater layer electrically isolated from a bilayer consisting of Fe $_{3}$ O$…

Effect of Interface Induced Exchange Fields on Cuprate-Manganite Spin Switches

Yaohua Liu, C. Visani, N. M. Nemes +8

We examine the anomalous inverse spin switch behavior in La $_{0.7}$ Ca $_{0.3}$ MnO $_{3}$ (LCMO)/YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ (YBCO)/LCMO trilayers by combined transport studies and polarized…
