Stability Intervals

Spontaneous and magnetic field-induced phase transitions in a rigid domain structure of a uniaxial ferrite-garnet film are studied. It is shown that the temperature and field stability intervals of the lattice of cylindrical magnetic domains depend on the structure of the domain boundaries.

AbstractPossible magnetic states of a cubic ferromagnet with a uniaxial anisotropy induced along the [210] direction are theoretically investigated. It is demonstrated that the orientation phase diagram of a magnet is nontrivial and admits the existence of three types of magnetic phases that differ in transformational properties and the presence of quintuple points, isostructural phase transitions, etc. It is found that magnetic inhomogeneities, regardless of the values of parameters of the matter, have a common structure: they correspond to 180-degree domain boundaries with a noncircular trajectory of the magnetization vector. The features of homogeneous and inhomogeneous magnetic states, found in these materials, make it possible to explain the manifestation of a flexomagnetoelectric effect in them.

Magnetic Compensation

The peculiarities of domain structures (DS) have been investigated in the two-layer film of (YGdTm)3(FeGa)5O12/(YEu)3(FeGa)5O12 composition with a magnetic compensation point (TC) in one of the layers and in the single-layer witnesses-films. It is shown that a change in the ratio of energies of magnetostatic and exchange interactions between the layers under temperature change induces a phase transition (PT) in the domain structure and a spin-reorientation phase transition (SRPT).

Nonlinear Magnetization

The calculations and experimental studies have shown that the intensity of nonlinear magnetization oscillations arising during the process of 180 pulsed magnetization reversal of real ferrite-garnet films with biaxial anisotropy weakly depends on the magnetization reversal pulse Hp frontf duration (in contrast to magnetic materials with uniaxial anisotropy). The pulsed magnetization reversalcurve, which provides a visual representation of the magnetization reversal speed saturation caused by the influence of nonlinear magnetization oscillations, analyzed for the first time.
