Field-cooling effect in biquadratically interlayer-coupledFe∕Cr∕Fetrilayers

Abstract

We report on the modified magnetic properties of an epitaxial Fe/ Cr/ Fe trilayer when it is cooled in an applied magnetic field. Magnetization measurements are carried out to investigate the dependence of the field-cooling effect on the magnetic field strength and on the temperature. Perturbed angular correlation experiments are performed to study the microscopic origin of the field-cooling effect.
