Anisotropy, critical current and dynamics of vortexes in high temperature superconductors

High temperature superconductors ErBa321Cu331O3x1, DyBa321Cu331O3x1, Bi321CaSr321Cu321O3x1 are considered in the paper aiming at the investigation of the conduction anisotropy, magnetoresistance, current critical density and relaxation effects. As a result the relaxation logarithmic dependence of the Bi321CaSr321Cu321O3x1 monocrystal magnetic moment has been established. The improved methodology of the critical current anisotropy determination has been suggested and realized. The results obtained may be used while creating of devices on the base of high temperature superconductorsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
