Summary

SUPERCONDUCTING SAMARIUM-BARIUM-COPPER-OXIDE STRIPS WERE PREPARED BY RAPID QUENCHING FOLLOWED BY ANNEALING. THE EXPERIMENTAL RESULTS ON MAGNETIC SUSCEPTIBILITY AND RESISTANCE REVEALED THEIR ANOMALOUS BEHAVIOUR AT TEMPERATURES ABOVE 140 THE CRITICAL FIELD WAS ESTIMATED TO BE EQUAL TO ZERO FOR CRITICAL TEMPERATURE APPROXIMATELY 356 K. FOR ROOM TEMPERATURE, THE CRITICAL CURRENT OF 0.00007 A AND RESISTANCE JUMP HIGHER OR EQUAL TO 900 MILLIONS WERE OBTAINED. SUSCEPTIBILITY SHOWED DIAMAGNETIC BEHAVIOUR UP TO 337 K. THE ABOVE ANOMALOUS BEHAVIOURS IN THE SAMPLES MEASURED WERE OBSERVED FOR 4 WEEKS.
