Perspectives on magnetic/superconductor hybrid systems: Long-range electromagnetic phenomena induced by proximity effect and interfacial spin–orbit coupling

Abstract

In this Perspective, we review recent achievements in physics and applications of hybrid superconductor–ferromagnet structures. In particular, we focus on the manifestations of the electromagnetic phenomena in these systems originating from the response of the induced superconducting correlations modified by the exchange field and additional effects coming from the interface Rashba-type spin–orbit coupling. The review includes the long-range electromagnetic proximity effect and related modification of magnetic textures, spontaneous currents, and properties of vortex matter and its interaction with magnetic ordering, spin-galvanic, photogalvanic, and nonreciprocal transport phenomena in exemplary hybrid systems. We also present our views on the future development of this field, including both the theoretical challenges and promising opportunities for fundamental experiments.
