We investigate the influence of dipole interaction on the phase transitions due to temperature variation in two‐dimensional ferromagnets. The spectra of quasi‐particles at the points of the phase transitions from “the easy‐axis phase” to “the angular phase” and from “the easy‐plane phase” to “the angular phase” are obtained. The temperatures of the phase transitions are found. The numerical evaluation of the temperature interval of angular phase existence is in good agreement with experimental data.
