The magnetoelectricity of samarium iron garnet is theoretically investigated: the antiferroelectric structures ions are described and their connection with configurations magnetic moments transformations during phase transitions revealed. possibility appearance at low temperatures unusual Bloch domain walls, in which magnetization vector rotates from [u v 0] axes to [v u axes, not crystal symme...

The effects of water and iron content on the relative creep strengths of garnet and olivine were investigated by shear deformation experiments. arnet and olivine samples were sandwiched together between alumina pistons in a simple shear geometry and were deformed at P= 1–2 GPa, = 1473 K and strain rates ranging from 10−5 to 10−3 s−1 using a Griggs-type solid-medium apparatus. The stressand stra...

Using a fast silicon strip detector, a multi-frame acquisition scheme was implemented to perform energy-dispersive X-ray magnetic circular dichroism at the iron K-edge in pulsed high magnetic fields. The acquisition scheme makes use of the entire field pulse. The quality of the signal obtained from samples of ferrimagnetic erbium iron garnet allows for quantitative evaluation of the signal ampl...

The possibility of intense radiation short-wave exchange spin waves excited in a thin transition layer at the internal boundary bilayer ferrite-ferrite structure is shown. Modelling processes has been exemplified by tangentially magnetized film ferric-yttrium garnet. It was found that one-way character. were radiated into with decreased magnetization. Their group velocities an order magnitude l...

Magneto-optical Faraday effect of Bi-substituted yttrium iron garnet (Bi:YIG) films with random multilayer structures was analyzed by using the random matrix approach. It was found that the random multilayer structure is very effective for enhancing the Faraday effect of the Bi:YIG film, which is much superior than that of the periodic multilayer films.

We demonstrate the dispersive measurement of ferromagnetic resonance in a yttrium iron garnet sphere embedded within a microwave cavity. The reduction in the longitudinal magnetization at resonance is measured as a frequency shift in the cavity mode coupled to the sphere. This measurement is a result of the intrinsic nonlinearity in magnetization dynamics, indicating a promising route towards e...

The chaotic self-generation of short solitary spin wave pulses has been observed for the first time. The pulses were produced from parametrically excited spin waves in an yttrium-iron-garnet film in an active feedback ring under conditions where both three-wave and four-wave parametric processes were allowed. The power-frequency spectrum was broadband and chaotic.

We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...
