Abstract

The transition to the ordered state of a magnet with the magnetic anisotropy of the effective g-factor due to the rotation of the external magnetic field from the axis with the maximal value of the effective g-factor to the axis with the lover value of it. It is shown that the predicted scenario can be realized in rare-earth isolating magnetic systems with the low (lower than 1 K) temperature of the transition to the magnetically ordered state.
