AN INVESTIGATION OF THE MAGNETIC APPLICATIONS OF SUPERCONDUCTING CERAMIC MATERIALS.

Superconducting ceramic materials have unique electrical and magnetic properties that make them suitable for a wide range of applications, including high-field magnets, microwave filters, and magnetic resonance imaging (MRI) systems. In this paper, we review recent developments in the field of superconducting ceramic materials and their potential use in magnetic applications. The discovery of high critical temperature superconducting (SAT) ceramic materials with T_c≈100 K has opened new perspectives for the application of superconductivity in many areas, including electronics. By moving the operating temperature from the liquid helium to the nitrogen range, cooling costs are reduced by several orders of magnitude. Despite the granular nature and other specific problems of SATs, and only five years after their discovery, superconducting wires and devices based on thin films are a reality. In this paper, we review the status of large and small-scale applications for SATs.
