The transport critical current / c of more than 100 samples of high temperature superconductor bulk material was measured as a function of temperature using a contactless magnetic induction method. All samples (mainly YBa2CH3OT\_ ~, but also TI-Ba-Ca-Cu-O and (Bi, Pb)-Sr-Ca-Cu-O) show a temperature
We have measured the magnetic flux in YBa2Cu30F superconductors when transport currents were allowed to flow in zero external field at 77 K. The magnetic flux was trapped when the transport current exceeded a value /cs, which was smaller than the transport critical current let; typically, 0.4/ct. We
High critical current densities at the level of magnetic field needed for specific operation, is an important prerequisit for the application of all kinds of superconductors. The discovery of the high Tc superconductors created enormous new hopes for a much broader breakthrough for superconductivity
