Abstract
The ferromagnetic resonance (FMR) and the magnetization switching fields have been analytically determined for weakly coupled Magnetic Tunnel Junction or spin valve systems. Such systems consist of an antiferromagnetic (AF) and two ferromagnetic (F) thin films separated by a nonmagnetic one. Both bilinear [Formula: see text] and biquadratic [Formula: see text] coupling parameters are used to describe the interlayer exchange coupling, while the exchange anisotropy field [Formula: see text] characterizes the interfacial ([Formula: see text]/AF) interaction. It will be shown how [Formula: see text], [Formula: see text], [Formula: see text] and the in-plane anisotropy fields can be derived for the experimental measure of the FMR field and the different magnetization switching fields.
