Abstract
A method for evaluating the temperature-dependent magnetic anisotropy field from thermomagnetic curves for Stoner-Wohlfarth-like systems is proposed, It allows the anisotropy parameters of a sample with unknown spontaneous ma gnetization to be obtained by using magnetic fields considerably lower than the anisotropy field.
