Influence of the mechanic boundary conditions on the dynamic and static properties of the ferromagnet with competing anisotropies

The phase transitions on the material constants in a semi-infinite ferromagnet with mechanic boundary conditions and competing "inclined" ease-axis anisotropy and easy-plane anisotropy have been investigated. The phase states and the spectra of coupled magnetoelastic waves have been researched. The analysis of the spectra of elementary excitations allowed the construction of the phase diagram of the system. - Highlights: • This article analyzes the influence of boundary conditions on the system's properties. • It is shown that the QU and IFM phases can be realized in the researched system. • Phase transition between these phases is not reorientation. • The inclined anisotropy increases the effect of quantum spin reducing. • The phase diagram of the investigated system is built
