The evolutions of the uniaxial torque and magnetization with the applied magnetic field allow us to discriminate the sources of in-plane magnetic anisotropy in amorphous ribbons. In order to determine the magnetic anisotropy sources, a simple model has been developed for an inhomogeneous material. We apply this model to explain the quite different behavior observed in the evolution of the uniaxial torque amplitude with the applied magnetic field of two commercial Co-based amorphous alloys.
