Enhancement of the critical transport current density in a bulk high-temperature superconducting ceramics by means of thermomagnetic treatment

摘要

An optimal mode of thermomagnetic treatment of the materials and articles being in paramagnetic state is presented. The results given show the efficiency for application of this mode of thermomagnetic treatment and its combination with the technique of growing crystals from the melt to increase the density of the critical transport current in a bulk high-temperature superconducting ceramics.
