The information about cellular respiration and metabolism of malignant and healthy cells is presented. The working example of a custom made magneto-therapeutic device allows to realize inhibitory effect on oncopathology. Thus, as a result of the investigations the intense pulse low-frequency magnetic field exposure results to morphofunctional inhibition of HeLa cell line. [ABSTRACT FROM AUTHOR]

The researches of the giant magnetoimpedance effect has led to the creation of magnetic field sensors with a sensitivity of millioersteds. On the basis of multilayered ferromagnetic films developed at the UrFU a prototype of weak magnetic fields detector is created. The detector is assembled according to the lock-in amplifier circuit operating at a frequency of 10.7 MHz under the control of the program described in this paper. The program provides DDS control, ADC data reading, mathematical processing of data streams, displaying graphs in real time. [ABSTRACT FROM AUTHOR]

The study of the magnetoimpedance effect (MI) in thin film multilayered structures was done by the finite element numerical simulation method (FEM). Longitudinal MI effect (external field and flowing current are parallel to each other) and transverse magnetic anisotropy were considered. The influence of saturation magnetization, anisotropy field, induced magnetic anisotropy peculiarities, electrical conductivity of permalloy layers in a multilayered structure placed in an external magnetic field under the influence of high-frequency alternating current was investigated. The highest sensitivity of the three-layered [FeNi]/Cu/[FeNi] structure was achieved at the maximum saturation magnetization, the smallest magnetic anisotropy field and the lowest dispersion of local effective anisotropy. Assumptions for further improving the model for prediction of the features of the frequency dependence of the MI ratio were discussed. FEM method was shown to be useful for design of MI elements with requested responses. [ABSTRACT FROM AUTHOR]

Using the sudden disturbance approximation, we have obtained expressions for calculating the scattering spectra of an attosecond pulse on atomic anions, taking into account the magnetic component of the electromagnetic field. It is shown that when an attosecond pulse of the Gaussian form electromagnetic field interacts with an atomic anion, the second harmonic is generated in the scattering spectrum. The paper presents analytical dependence of the partial spectrum on frequency. The obtained expressions have an analytical form, which makes it possible to carry out the most complete analysis of the systems under consideration. It is shown that scattering patterns with regard to the magnetic component of the field have characteristic quantitative and qualitative differences. In practice, this means that by detecting the scattering spectra, one can predict the form and final states of the anions. [ABSTRACT FROM AUTHOR]

This work deals with theoretical approach and mathematical modeling of hyperthermia effect by single– domain ferro-nanoparticles. The magnetic particles have the Neel relaxation particles of the easy magnetization axes. The system is happened under external magnetic field. Two situations of systems, system of approximation of non-interaction chaotic particles like single particle and system of chain-like two particles are considered into account whereas these particles are in strong magnetic anisotropy. Our analysis shows the chain of particles with strong magnetic anisotropy weakens the thermal effect of hyperthermia under the effect of easy magnetization axes of ferro-nanoparticles.

The magnetocaloric properties of Gd ribbons processed by different kinds of mechanical treatments such as plastic deformation and ball milling were comparatively analyzed and discussed. The maximum of the temperature dependence of the magnetic entropy change for the ribbon in the initial state was as high as 11.8 J/kg•K in magnetic fields up to 7 T, i.e. it was very close to the corresponding value for the bulk gadolinium. The maximum values of the magnetic entropy change for the powder sample and the deformed sample in the same fields were as high as 3.2 and 1.9 J/kg•K respectively. [ABSTRACT FROM AUTHOR]

Features of nonlinear diffusion of high magnetic fields in conductive solids were studied. The derivation of the well-known solution of Bryant was found analytically for case an arbitrary dependence of the specific resistance on temperature. The magnetic field diffusion in a material with a more resistive surface layer was modeled numerically. According to calculations such a layer appreciably decreases local heating due to movement of maximum of current density inward the material. The two-layer structure is preferable for using in devices of high pulse magnetic field generation. [ABSTRACT FROM AUTHOR]
