1. Evaluation of the anisotropy field for fine-particle systems from low-field thermomagnetic curves
A method for evaluating the temperaturedependent magnetic anisotropy field from thermomagnetic curves for Stoner–Wohlfarth-like systems is proposed. It allows the anisotropy parameters of a sample with unknown spontaneous magnetization to be obtained by using magnetic fields considerably lower than the anisotropy field.
