Elastomagnetoresistive Properties of Films of 3d-Metalls Alloys

Magnetoresistive properties of 3d-metals alloys magnetostrictive films under application of elastic deformations were investigated. Linear stress was shown to have a significant effect on magnetoresistive effect in the films through the rotation of the easy magnetization axis. Dependencies of the relative change of resistivity were obtained in a cyclic deformation regime for films of different compositions

Elemental analysis of archaeological ochre: method and possibilities of X-ray fluorescence spectroscopy (based on materials of Neolithic and Aeneolithic sites of the Middle Trans-Urals and Western Siberia)

The article is dedicated to methodological aspects of the elemental analysis (X-ray fluorescence spectroscopy) of a natural mineral pigment — ochre. We chose oxide ochre obtained from the Neolithic and Aeneolithic sites of the taiga zone of Western Siberia and the Middle Urals (the end of VI — III millennium BC) as a source base. The questions of selection and preparation of archaeological samples, and of interpretive capabilities of the chosen approach are discussed in the article

Structure and magnetic properties of FeNi/Ti sputtered multilayers

The microstructure, anisotropic magnetoresistance, magnetic properties and magnetic domain structure of sputtered FeNi films and [Ti/FeNi]n (n = 2-16) multilayers were comparatively analyzed. It was found that although the grain size increases with an increase of the FeNi thickness both in the case of FeNi films and [Ti/FeNi]n multilayers, it did not exceed 25 nm. The values of anisotropic magnetoresistance for FeNi films and [Ti/FeNi]n multilayers were close to each other showing a weak dependence on the total thickness of the multilayered structure. Coercivity for multilayers was found to be smaller than the coercivity of single layer FeNi films. Despite the absence of a direct exchange interaction between FeNi neighboring layers in the [Ti/FeNi]n structures, their domain structures were found to be quite different from magnetic domains in single layer films due to stray field compensation in the multilayers. Obtained results are useful for the development of sensitive elements for small magnetic field detectors and planar inductors
