ANOMALIES IN THE TEMPERATURE DEPENDENCES OF THE RESISTIVITY, CRITICAL CURRENT AND CRITICAL MAGNETIC FIELD OF BARIUM (1-X) POTASSIUM (X) BISMUTH OXIDE (3).

[In Russian. / En russe.]

Type of article: Article

Summary

THE RESISTIVITY AND CURRENT-VOLTAGE CHARACTERISTICS ARE MEASUR ED AT TEMPERATURES BETWEEN 2 AND 300 K AND IN FIE BELOW THE CRITICAL TEMPERATURE THE RESISTIVITY DEPENDS CRUCIALLY ON THE CURRENT VALUE. THE < DIELECTRIC > INCREASE OF THE RESISTIVITY OBSERVED AT TEMPERATURE LOWER THAN CRITICAL TEMPERATURE IN THE PRESENCE OF < LARGE > CURRENTS EXCEEDS THE RESISTIVITY IN THE NORMAL STATE BY SEVERAL ORDERS OF MAGNITUDE ; IT CAN BE SUPPRESSED BY A MAGNETIC FIELD, THE RESISTIVITY ACQUIRING THE VALUE CHARACTERISTICS OF THE NORMAL STATE.
