Abstract
A jump in the frequency of the quasiferromagnetic soft mode in Fe3BO6 at the point of the spontaneous orientational phase transitions Γ2−Γ4 is observed experimentally. It is shown theoretically that this jump can be explained by the contribution of the dipole interaction to the expression for the quasiferromagnetic soft mode.
