**Abstract.
**The paper is devoted to the development
of the mathematical model of gyromagnetic hexagonal ferrite material.**
**The problem of calculation of static magnetization direction of the
single-domain hexaferrite particle in outer magnetic field is revised. The
problem solution is taking into account a possibility of existence of two
stable states of the magnetization vector. Method of choice one or another
state with accounting of the magnetization prehistory is proposed.** **An algorithm
for calculation of the magnetization curves and magnetic hysteresis curves with
accounting of the magnetization prehistory is developed. Method, proposed in
the algorithm, allows for calculating the magnetization curves by arbitrary
variation of the magnetic field with arbitrary orientation of the ferrite
particles.** **Proposed method appreciably simplifies the calculation of the
magnetization curves for polycrystalline materials.
