Magnetic Properties and Critical Current of Superconducting Nanocomposites (1 − x)YBa2Cu3O7−δ + xCuO
The aim of this paper was to study the effect of nanoscale inclusions of CuO as the second ingredient of composites on transport properties of superconducting YBa2Cu3O7 polycrystals. The samples of YBa2Cu3O7−δ with different ...
Localization and transfer of charge carriers in CuO nanopowder by impedance spectroscopy
Abstract Particular electro-physical characteristics of CuO nanopowder were investigated by impedance spectroscopy using a sensor based on interdigitated structure in the frequency range from 1 Hz to 100 MHz. The results ...
Device for Increasing the Magnetic Flux Pinning in Granular Nanocomposites Based on the High-Temperature Superconducting Ceramic
A device for modifying the granular high-temperature superconducting ceramics in the plasma of a low-pressure arc discharge has been considered. The particular features of the design and operational principle of this device ...
Study of Phase Composition of CuO/Cu2O Nanoparticles Produced in the Plasma of a Low-Pressure Arc Discharge
The influence of synthesis parameters on peculiar features of the forming crystalline phases of copper oxide nanoparticles is inspected via electron microscopy, IR spectroscopy, X-ray diffraction, and differential thermal ...
Two Types of Localized States in a Photonic Crystal Bounded by an Epsilon near Zero Nanocomposite
The spectral properties of a one-dimensional photonic crystal bounded by a resonant absorbing nanocomposite layer with the near-zero permittivity have been studied. The problem of calculating the transmittance, reflectance, ...
Magnetic resonance studies of mixed chalcospinel CuCr2SxSe4−x (x = 0; 2) and CoxCu1−xCr2S4 (x = 0.1; 0.2) nanocrystals with strong interparticle interactions
Magnetic resonance characteristics of mixed chalcospinel nanocrystals CuCr2SxSe4−x (x = 0 and 2) and CoxCu1−xCr2S4 (x = 0.1 and 0.2) have been investigated. It has been established based on TEM, SEM and resonance data that ...
