On features of magnetization self-organization in 1D stochastic ferromagnetic systems
The magnetic structure of a polycrystalline nanowire at the weak or missing magnetostatic interaction exhibits the special self-organization of magnetization. As is known, the magnetization structure forming in a random ...
New method for calculations of nanostructure kinetic stability at high temperature
A new universal method is developed for determination of nanostructure kinetic stability (KS) at high temperatures, when nanostructures can be destroyed by chemical bonds breaking due to atom thermal vibrations. The method ...
Establishing of peak effect in YBCO by Nd substitution
Y0.75Nd0.25Ba2Cu3O7−d superconductor has the peak effect with pronounced fishtail feature on magnetization hysteresis. The magnetic field of the peak effect maximum is in ~4 times higher than one of NdBa2Cu3O7−d. The ...
Tuning the peak effect in the Y1−xNdxBa2Cu3O7−δ compound
Polycrystalline Y1−xNdxBa2Cu3O7−δ (x=0.02, 0.11, and 0.25) superconductors are synthesized. Nd atoms are uniformly distributed over grains. The magnetization loops of the samples have a pronounced second peak in a wide ...
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 ...
On the origin of membrane potential in membranes with polarizable nanopores
We report a new mechanism for the generation of membrane potential in polarizable nanoporous membranes separating electrolytes with different concentrations. The electric field generated by diffusion of ions with different ...
