Abstract

The presented work shows the reality of recording anisotropic magnetoresistance signal in thin ferromagnetic films with uniaxial in-plane magnetic anisotropy under pseudoresonance conditions. Experimental data and calculations based on the Landau–Lifshitz–Hilbert equation demonstrate the ability of this technique to switch the signal sign by imposing an external constant magnetic field of ~ 1 Oe.
