Recording media are easier to record if the write field is applied at an angle to the easy axis owing to the angle dependence of the switching field. It is shown that both record modes, longitudinal and perpendicular recording, inherently use this an

The intrinsic damping mechanism arising from the magnon–magnon scattering is theoretically studied in three dimensional and two dimensional ferromagnets. We develop an analytic theory, which identifies the three-magnon (in bulk) and four-magnon (in

The effect of an exchange field on electrical transport in thin films of metallic ferromagnetic manganites has been investigated. The exchange field was induced both by direct exchange coupling in a ferromagnet/antiferromagnet multilayer and by indir

We fabricated perpendicular media with decoupled magnetic grains that consist of a low magnetocrystalline anisotropy layer with various thicknesses directly grown on top of a high anisotropy layer. Nonuniform magnetization rotation was confirmed by m

We study a two-dimensional motion of a charged particle in a weak random potential and a perpendicular magnetic field. The correlation length of the potential is assumed to be much larger than the de Broglie wavelength. Under such conditions, the mot

We have studied inelastic hot electron scattering due to interaction with neutral acceptors accompanied by their excitation and ionization. Comparative studies of narrow GaAs AlAs multiple quantum wells and bulk GaAs films were performed in the conce

The polarization characteristics of hot photoluminescence in GaAs/AlAs superlattices are investigated experimentally and theoretically. It is shown that the formation of an electronic miniband in the superlattice substantially changes the polarizatio

A unidirectional magnetotransport anisotropy observed in thin films of exchange-biased ferromagnetic manganites is used to measure temperature dependence of exchange bias in these structures. Values of both the exchange field and the blocking tempera

Using numerical and analytical micromagnetics we calculated the switching fields and energy barriers of the composite (exchange spring) magnetic recording media, which consist of layers with high and low magnetocrystalline anisotropy. We demonstrate
