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 ...
Dynamic Magnetization Switching in NiO Nanoparticles: Pulsed Field Magnetometry Study
The dynamic magnetization switching of antiferromagnetic nickel oxide nanoparticles with a characteristic size of 8 nm has been experimentally investigated by pulsed field magnetometry. It is shown that, due to the presence ...
Superconductivity on Interfaces of Nonsuperconducting Granules La2CuO4 and La1.56Sr0.44CuO4
Composite materials fabricated by annealing of nonsuperconducting ceramics La2CuO4 and La1.56Sr0.44CuO4 at 910 °C during various time are investigated. Areas of superconducting La1.85Sr0.15CuO4 phase arises at boundaries ...
BACTERIAL FERRIHYDRITE NANOPARTICLES: PREPARATION, MAGNETIC PROPERTIES, AND APPLICATION IN MEDICINE
Nanoparticles of antiferromagnetically ordered materials acquire the uncompensated magnetic moment caused by defects and surface effects. A bright example of such a nanoantiferromagnet is nanoferrihydrite consisting of ...
Synthesis of the Orthorhombic Dy1-xHoxMnO3 Single Crystals and Study of Their Magnetic Properties
In this report we prepared for the first time the orthorhombic Dy1-xHoxMnO3 single crystals with x = 0, 0.1, 0.2, 0.3, and 0.4 using the flux technique. The post-growth processing and chemical and structural characterization ...
