On the basis of electric field-current density (E-j) isotherms experimentally determined on YBaCuO thin film microbridges, the previously assumed separation ansatz U(T, Be,j) = g(T, Be)Uj(j) for the activation energy for flux motion is tested over a

Measurements of the fundamental ac-susceptibility provide a sensitive tool to study the shielding behavior of ceramic high-T c superconducting material. In this work, ac-susceptibility data for differently prepared YBaCuO-samples are presented. From

High quality flux grown and defect enriched peritectically grown YBa2Cu3O7−x single crystals have been investigated by an ac-susceptibility technique. This method allows to determine an irreversibility line from the temperature and field dependence

Applying an a.c.-susceptibility technique, the lower critical fields Hc1(T) as well as the irreversibility lines Hc*(T/Tc) ~ (1 - T/Tc)α have been determined for YBaCuO and Tl2Ba2CaCu2O8 single crystals. Pronounced anisotropies are observed for the

A new ac technique based on the nonlinear magnetic response of sintered YBaCuO material is introduced to determine quantitatively the zero‐field‐cooled and field‐cooled remanent magnetization of this high Tc superconductor. It is demonstrated t

It has been reported recently by Braunisch et al. [Phys. Rev. Lett. 68, 1908 (1992)] that some ceramic high-${\mathit{T}}_{\mathit{c}}$ superconductors (HTSC's) exhibit a paramagnetic signal if cooled through the superconducting transition temperatur

A specially designed ac-susceptometer is described, which allows one to determine the anisotropy of the magnetic response of small (0.08×0.5×0.6mm) HTSC-crystals or thin films. The technique is illustrated by two examples: 1. Determination of the p

By measuring the time dependence of a supercurrent induced in a ring patterned YBaCuO-film with a specially designed SQUID-magnetometer, isothermal current voltage (I–V)-characteristics can be determined. Combining this technique with standard tran
