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 ...
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 ...
Pulsed Field-Induced Magnetization Switching in Antiferromagnetic Ferrihydrite Nanoparticles
The dynamic magnetization switching of ferrihydrite nanoparticles has been investigated by a pulsed magnetometer technique in maximum fields Hmax of up to 130 kOe with pulse lengths of 4, 8, and 16 ms. Ferrihydrite exhibits ...
