Abstract
A study of the influence of the processing conditions of Ag-Bi2Sr2CaCu 2Ox screen-printed tapes on the temperature, field and frequency depen dence of their a.c. susceptibility has been conducted. Samples have be en prepared by melt-solidification and subsequent sintering on silver substrates under the same conditions but with different cooling proced ures and reannealing. These procedures lead to different T(C) values a nd field dependency of the loss peak temperature T(M), which cause the crossover in the T(M) versus applied field characteristics. It was es tablished that the above crossover phenomenon is correlated to the cro ssover in the J(C) versus temperature characteristics.
