摘要：

To determine the anisotropy field HA of hard magnetic materials the singular point detection method can be applied. In single crystals the height and the position of the maximum of |d2M/dH2| very sensitively depend on small deviations of the external field from the hard direction. On the other hand, in polycrystalline samples the singularity is replaced by a cusp exactly at H = HA, and the height of the cusp changes rather slowly with the field direction.
