| 摘 要： | The resistivity and magnetic susceptibility ofthe quenched samples for the Y-Ba-Cu oxideswere measured at room temperature.Themeasurement for the temperature dependence of theamorphous Bi-Sr-Ca-Cu oxides with differentheat treatment temperature was made.Theresistivity and the parameters C in the formulax=X_0+C/(T-0)of the quenched samples forY-Ba-Cu oxides decreased with lowering quenchtemperature,and their susceptibility did not varymonotonously with quench temperature.The tem-perature dependence of the amorphousBi-Sr-Ca-Cu oxides gradually deviates fromCurie-Weiss law with increasing heat treatmenttemperature.The local magnetic moments forY-Ba-Cu and amorphous Bi-Sr-Ca-Cu oxidesgradually decrease with decreasing quench tempera-ture or increasing heat treatment temperature.

| Abstract: | The resistivity and magnetic susceptibility of the quenched samples for the Y-Ba-Cu oxides were measured at room temperature.The measurement for the temperature dependence of the amorphous Bi-Sr-Ca-Cu oxides with different heat treatment temperature was made.The resistivity and the parameters C in the formula x=X_0+C/(T-0)of the quenched samples for Y-Ba-Cu oxides decreased with lowering quench temperature,and their susceptibility did not vary monotonously with quench temperature.The tem- perature dependence of the amorphous Bi-Sr-Ca-Cu oxides gradually deviates from Curie-Weiss law with increasing heat treatment temperature.The local magnetic moments for Y-Ba-Cu and amorphous Bi-Sr-Ca-Cu oxides gradually decrease with decreasing quench tempera- ture or increasing heat treatment temperature. |
