We investigate interlayer exchange coupling based on driving a strong/weak/strong ferromagnetic trilayer through the Curie point of the weakly ferromagnetic spacer, with exchange coupling between the strongly ferromagnetic outer layers that can be switched on and off, or varied continuously in magnitude by controlling the temperature of the material. We use Ni-Cu alloys of varied composition as the spacer material and model the effects of proximity-induced magnetism and the interlayer exchange…
