Proximity-enhanced magnetocaloric effect in ferromagnetic trilayers

Journal of Physics: Condensed Matter, 2022
Abstract The demagnetization and associated magnetocaloric effect (MCE) in strong-weak-strong ferromagnetic trilayers, upon a reorientation of the strong ferromagnets from parallel to antiparallel (AP) magnetization, is simulated using atomistic spin dynamics. The simulations yield non-trivial spin distributions in the AP state, which in
