Macroscale non-local transfer of superconducting signatures to a ferromagnet in a cavity
arXiv:2006.12516 · doi:10.1103/PhysRevB.102.180506
Abstract
Cavity spintronics recently heralded non-local magnonic signal transfer between magnetic samples. Here we show that by including superconductors in the cavity, we can make use of these principles to bring composite superconductor--ferromagnet systems to the macroscale. We analyze how a superconductor's a.c. conductivity influences the spin dynamics of a spatially separated magnet, and we discuss the potential impact on spintronic applications.
