摘要：
A study of the influence of the processing conditions of Ag-Bi2Sr2CaCu2Ox screen-printed tapes on the temperature, field and frequency dependence of their a.c. susceptibility has been conducted. Samples have been prepared by melt-solidification and subsequent sintering on silver substrates under the same conditions but with different cooling procedures and reannealing. These procedures lead to different T(C) values and field dependency of the loss peak temperature T(M), which cause the crossover in the T(M) versus applied field characteristics. It was established that the above crossover phenomenon is correlated to the crossover in the J(C) versus temperature characteristics.
