Magnetic anisotropy and ferromagnetic resonance in inhomogeneous demagnetizing fields near edges of thin magnetic films.

Using local ferromagnetic resonance spectroscopy, we have studied the magnetic properties near edges of thin tangentially magnetized permalloy films, in which a well-defined uniaxial magnetic anisotropy was induced perpendicular to one of the edges. In the experiment, two samples with thicknesses of 90 and 300 nm and with slightly different compositions were examined. To explain the magnetization dynamics near edges, we propose a simple yet effective model of a film in the form of a rectangular prism, which yields the modified Kittel formula for the resonance frequency.

Numerical study of structural and magnetic properties of thin films obliquely deposited on rippled substrates.

Structural modulation in thin films plays a substantial role in the formation of their magnetic properties. By producing topographic patterns in thin films, it is possible to engineer their magnetic response. Here, we report on the numerical study of the relationship between structural and static magnetic properties of thin films obliquely deposited on substrates with the sinusoidal surface.

Microstrip resonator for nonlinearity investigation of thin magnetic films and magnetic frequency doubler.

A structure that consists of a λ/4 stepped-impedance microstrip resonator is proposed as an instrument for the investigation of nonlinear effects in thin magnetic films and also can be used as a microwave frequency doubler. A conversion efficiency of 0.65% is observed at a one-layer 100 nm NiFe thin film at an input signal level of 4.

[The use of synthetic glycoconjugates as components of the immunochromatographic test for rapid serological diagnosis of leprosy.].

The glycoconjugates with BSA (bovine serum albumin) were synthesized using a next saccharide: disaccharide derivative M.leprae PGL-1 (phenolic glycolipid-1); a complex of the disaccharide fragment and the branched hexasaccharide fragment LAM (lipoarabinomannan); diarabinofuranose fragment LAM. These glycoconjugates were used as antigenic components for leprosy rapid serotest construction in immunochromatographic format (leprosy LF serotest).

[The hemodynamic effect on the spatial organization of atherosclerotic lesions in the human aorta. Plaques at the sites of arterial branching].

By means of light microscopy of whole-mounted membranous preparations and scanning electron microscopy differences of the three-dimensional organization in the macroscopically intact and atherosclerotic human aortic intima in the sites of intercostal artery ostium were investigated. It was shown that the process of atherogenesis begins in the lateral areas and later involves the site of the entry. The flow divider does not contain lipids and resembles fibrous cap of the plaque.
