Abstract. Multi-regime character of magnetization equilibrium position precession in two-sublattice ferromagnetic with compensation point is investigated. The phase diagram is constructed. It is found and solved the equations system for magnetization precession of both sub-lattices. The evolution in time of magnetization components and proper precession portraits are constructed. It is shown that magnetization equilibrium position precession on field is possible only between lower and upper branches of phase diagram. It is found four regime of magnetization equilibrium position precession: regime ¹1 – small amplitude circular precession; regime ¹2 – precession without center encircle; regime ¹3 – precession with center encircle; regime ¹4 – unfolded circular precession. The value of equilibrium magnetization precession period by variation of different task parameters is investigated. It is shown that by increasing of alternating field amplitude the equilibrium magnetization precession period is decreased. It is shown that by increasing of constant field amplitude the equilibrium magnetization precession period is increased. It is shown that by increasing of alternating field frequency the equilibrium magnetization precession period is decreased. It is shown that by variation inside of phase diagram region the exchange parameter between sub-lattices the equilibrium magnetization precession period remains constant. It is proposed some recommendations for further development of investigations.
