Abstract

The anisotropic nature of the resistivity of magnetic multilayers under a parallel or perpendicular applied magnetic field is addressed by magnetoresistivity and hysteresis loop measurements. It is shown that the observation of anisotropic magnetoresistance (AMR) at 80 K can provide straightforward information on the magnetic properties of successive layers in Fe/Pt multilayers. The relative as well as absolute Fe and Pt thicknesses are critical for the AMR behaviour. For Fe layer thicknesses tFe less than 5 AA both rho /sub /// and rho perpendicular to increase initially as a function of the applied field H while for larger tFe rho perpendicular to always decreases. The anomalous AMR for t Fe<5 AA is attributed to an inclination of the Fe magnetization out of the film's plane.
