We investigate the dynamics of a system of nanomagnet coupled to the Josephson
junction. The manifestation of the Kapitsa pendulum features in such a system is
studied. The role of quasiparticle current on the change of frequency dependence in
the Kapitsa-like pendulum features is revealed. We also investigate the effect of
external radiation on the properties of the Kapitsa pendulum...
Metal-organic frameworks (MOFs) are crystalline materials consisting of an infinite network of metal-ions, or metal-ion clusters, bridged by organic ligands through coordination bonds into porous two- or three- dimensional extended structures. MOFs are attracting increasing interest due to their unique properties such as magnetism, luminescence, high catalytic activity, gas storage and so on....
Being a sensitive probe for structural imperfections, the ion beam induced luminescence is efficient tool for real-time characterization of irradiating materials. In particular, registration of the luminescence decay after single ion impact may provide very interesting information about dynamics of dense electronic excitations in vicinity of swift ion trajectory. Temporal resolution in such...
Ion beam irradiation is a versatile tool for structural modification and engineering of new materials, where the energy of ions dictates the nature of interactions between accelerated ions and the target. In this study, 12-tungstophosphoric acid (WPA) films of different thickness were spin-coated on platinized silicon substrate and irradiated with: low energy light ions (H- and C+) with...
Silicon nitride is one of the perspective ceramics for inert matrix fuel hosts to be used for transmutation of minor actinides. Such materials should have structural stability and appropriate mechanical properties being irradiating with neutrons, α-particles and fission products.
In this work we report on mechanical properties of polycrystalline Si3N4 irradiated with swift heavy ions...
One of the most actual problem at the physics of low-dimensional superconducting/ferromagnetic heterostructures is determination of the correlation between magnetic spatial profile and the spatial profiles of the elements at the interface between layers. Standard neutron reflectometry can’t be used to measure neutron interaction with separate element, in particular, magnetic field induction. A...
Bi2WO6 is the simplest member of the Aurivillius family, but it possesses many interesting physical properties such as ferroelectricity with large spontaneous polarization and high Curie temperature (Tc=960), piezoelectricity with a potential for high-frequency and high temperature applications, high ion conductivity and photocatalytic activity. But apart from potential application, bismuth...
The wide range of technological applications of phosphate glasses enable them to occupy high rank in the science of glass. This is due to, the ease of network modification of the phosphate glasses via additive other modifiers character, low glass transition temperature, high thermal expansion coefficient, high electrical conductivity and very high transmission in the ultraviolet region. These...
The study of the structural properties of non-compact colloidal associates, as well as linear and branched polymers, is an important task of modern physical chemistry, since the structure at the nanoscale determines a number of important macroscopic features. Such systems often have fractal properties, that is, they exhibit scale invariance in a number of characteristics.
The development of...
