Effects of intense magnetic field on the properties of magnetic ions are discussed briefly. Details of the researches on the magnetic properties of some compounds under intense magnetic field are presented. In Fe_7S_8, orbital angular momentum is not quenched and the direction of the magnetic spin is inclined to the basal plane of a pseudo-hexagonal lattice. Magnetic anisotropy energy of Fe_7S_8 is deduced from the magnetization curve under the intense field as high as 100 kOe. In Au_2Mn a transition from antiferromagnetic helical spin structure to a ferromagnetic is observed and the induced magnetostriction is measured. In α-Fe_2O_3 Single crystal, a magnetic field-induced transition from an antiferromagnetic to a weak ferromagnetic and then to the antiferromagnetic is observed. The results of measurements are analyzed on the basis of magneto-crystalline coupling in a rhombohedral lattice. In the compound MnHg, a gradual change of susceptibility is observed at 200°K. This change is accompanied with a deformation of lattice and can not be regarded as a Neel point, based on the measurements of high field susceptibility and specific heat. In Cr-modified Mn_2Sb, the variation of transition point from antiferromagnetic to ferrimagnetic state with magnetic field is observed. A mechanism of the transition is proposed on the basis of a temperature dependent variation of the molecular field coefficient, and the exerimental results are analyzed.
