Thermally induced antiferromagnetic exchange in magnetic multilayers
arXiv:1706.06325 · doi:10.1103/PhysRevB.96.104427
Abstract
We demonstrate sharp thermally-induced switching between ferromagnetic and antiferromagnetic RKKY exchange in a spin-valve with the spacer incorporating a thin diluted ferromagnetic layer as the core. We illustrate the mechanism behind the effect as due to a change in the effective thickness of the spacer induced by the Curie transition into its paramagnetic state.
