Abstract
In this work we report on the experimental and theoretical investigations of the effects of various magnetic couplings existing in spin-valve structures. Magnetic interactions such as the exchange bias that occurs at the ferromagnetic/antiferromagnetic interface and the indirect coupling between ferromagnetic (FM) layers mediated by a nonmagnetic metal spacer as well as the interchange between both kinds of interactions were investigated. The unidirectional anisotropy that pins the magnetization of the pinned layer transmits to the free layer throughout the nonmagnetic spacer. Also, the resonance fields of the FM layers show an upward (downward) shift for an antiferromagnetic (ferromagnetic) bilinear coupling.
