Abstract. By dynamic establish method the forming of thin film phase diagram from two-lattice ferromagnetic with compensation point is investigated. It is shown that the constant field variation of both sub-lattice magnetizations consists of two phase transitions which are divided by orientational transition. It is described the phase diagram procedure construction by variation of transition fields on temperature and also by determined values of anisotropy and demagnetization. It is shown that the temperature increasing leads to narrowing of diagram on field up to complete branches unite by the reaching of anisotropy constant critical value. It is found that near the compensation point the united branch splits and diagram forms in closed region limited from both sides by temperature and field. It is established the diagram formation in closed region criterion which is consist of correlation of critical anisotropy value with region of smooth lowering on temperature. It is considered the correlation between received results with experiment. It is shown that the calculated diagram has appearance of closed region which is placed on field and temperature in the same limits as experimental. It is proposed some recommendations for further development of investigations.

Keywords: phase diagram, two-sublattice ferromagnetic, dynamical establishment method.
