Ferrite phase shifters using stress insensitive garnet materials
1994 IEEE MTT-S International Microwave Symposium Digest (Cat. No.94CH3389-4), 1995Stable hysteresis characteristics of ferrimagnetic materials are critical to the RF performance of microwave ferrite toroidal phasers. Particularly troublesome are the magnetostrictive characteristics where the hysteresis properties are altered by stress.

Phase Transitions in the Two-Layer Ferrite-Garnet Film
Solid State Phenomena, 2014The 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

Domain structure of (011) crystalline garnet ferrite plates
Technical Physics, 2003The domain structure in (011) crystalline garnet ferrite plates is studied with allowance for induced uniaxial anisotropy and two-constant cubic anisotropy. It is shown that the inclusion of the second constant of cubic anisotropy greatly affects the orientational phase diagram and also the topology of magnetic inhomogeneities in a given magnet.

Microinhomogeneities in the distribution of oxygen concentration in ferrite-garnet films
Physics of the Solid State, 1999Artificial microinhomogeneities were created in iron-garnet (TmBiCa)3(FeGa)5O12−γ films with various degrees of oxygen nonstoichiometry, changes in the individual magnetic characteristics of these inhomogeneities were tracked during chemical oxidation and reduction, and the interactions of these inhomogeneities with planar domain walls and spiral ...

Magnetooptical effects in bismuth-containing ferrite-garnet films
Soviet Physics Journal, 1989We present results of magnetooptical investigations of bismuth-containing ferrite-garnet films with the easy axis of magnetization parallel to the specimen surface. Measurements were conducted for incident light with energies in the range 1.5–3.2 eV for transverse [equatorial Kerr effect (EKE)] and for longitudinal [meridional intensity effect (MIE ...

Heat capacity of ferrite-garnet nanowire with domain wall
Physica B: Condensed Matter, 2019Abstract Formalism is proposed for studying of the thermodynamic properties of ferromagnetic nanowires, on the basis of which it is established that at temperatures below the Debye temperature the contribution of a domain wall to the heat capacity of ferrite-garnet nanowires can exceed the phonon and magnon contributions.

The peculiarities of bubble structures in ferrite-garnet films
2018Peculiarities of the disordered bubble structures under temperature or magnetic field change have been studied. The experimental results are interpreted with in the concept of magnetistatic pressure. It is shown that the "memory effect" and the temperature range of stability depend on the degree of domain structure disorder and on structure of domain ...
