摘要：

The effect of hydrostatic pressure on the hexagonal basal magnetic anisotropy of a rhombohedral easy-plane weak ferromagnet is investigated in terms of the thermodynamic theory. It is shown that the contribution to the hexagonal anisotropy is determined by the effective constants of the uniaxial and cubic anisotropy, which include the additions proportional to the hydrostatic pressure. The hydrostatic pressure, which leads to the basal anisotropy observed in experiments for stressed samples, is determined for hematite.
