It is predicted theoretically that the magnetic linear birefringence will be a linear function of the field in a paramagnetic rare-earth compound, in which the ground state of the rare-earth ion is an isolated doublet, in a strong magnetic field. The theoretical predictions are confirmed by experiments with erbium aluminate garnet.
