The spin-valve complex magnetoimpedance of symmetric ferromagnet–normal-metal–ferromagnet
junctions is investigated within the drift-diffusion (standard) model of spin injection. The ac magnetoresistance—the real part difference of the impedances of the parallel and antiparallel magnetization configurations—exhibits an overall damped oscillatory behavior, as an interplay of the diffusion and ...
