Raw materials and equipment were obtained and new high temperature superconductors (HTSC'S) were fabricated. YBCO material showed promising response to a 1T electromagnetic field. Three methods of quenching superconductivity examined. Four-point measurement technique used. HTSC samples were long bars of bulk material with silver contacts, YBaSaCaO material has 200 times higher normal state resistivity than YBCO, but low current density. Pulsed current quenching experiment caused sample to quench immediately, but ...
