The behavior of a hexagonal bubble lattice in a (BiTm)3(FeGa)5O12 garnet ferrite uniaxial film with a compensation point of 120 K is investigated experimentally in the range of the crossover from easy-axis magnetization anisotropy to easy-plane magne

The behavior of a hexagonal lattice of bubble domains in thin uniaxial films of garnet ferrites is studied in the temperature range from the compensation point to the Neel temperature. Two types of first-order phase transitions (preserving and not pr

Static properties of spiral domains forming a two-dimensional hexagonal lattice are investigated theoretically. A total energy density and its equilibrium parameters (number of spiral coils and period of the structure) are calculated. The energy of t

The coexistence of two domain phases, namely, a spiral domain and a bubble-domain lattice, is investigated experimentally in thin garnet ferrite films with uniaxial anisotropy. The condition for this coexistence is shown to be the equality of the mag

The properties of a new domain structure, the equilibrium hexagonal lattice of spiral domains in ferrimagnetic films with perpendicular anisotropy were experimentally studied. The intervals of the bias fields and temperatures under which the lattice

Order—order and order—disorder phase transitions in the domain structure of ferrite—garnet films upon a change in temperature or magnetic field were studied. It was shown that the structure of the domain boundaries affects the type of the phase

The temperature behavior of the domain structure in a two-layer ferrite-garnet film with one of the layers having a compensation point Tc, as well as in single-layer witness films, has been experimentally investigated. It is shown that the rare earth

Observations of the coarsening of two-dimensional cellular domain patterns with increasing film temperature at a constant bias field in magnetic garnet films are reported. It is shown that during this coarsening the value of the relative film magneti

The possibility of coexistence of a magnetic bubble lattice (MBL) and a stripe domain structure (SDS) as two domain phases of a thin magnetic film at various temperatures has been studied from the point of view of the balance their magnetostatic pres

By virtue of minimization of a phenomenological expression for the free energy of domain structures of soft magnetic films the conditions under which the amorphization of domain structures takes place are found. It is shown that domain structure orde
