摘要：

We have studied the variation of low field magnetization hysteresis in YBa2Cu3O7 as a function of the maximum magnetic field applied during a hysteresis cycle (1 G<H max<7.3 G) and also as a function of temperature (77 K<T<95 K). The remnant magnetization is studied as a function of H max and T and the measured dependences are explained using the extended critical state model. The potential of this technique as a contactless method of probing the temperature dependence of J c is discussed. © 1990 the Indian Academy of Sciences.
