Abstract
Temperature and magnetic field dependences of pinning parameters connected with J(c) distribution are obtained from measurements on electric field-cur rent density characteristics. A scaling law of the pinning force is confirm ed. The temperature dependences of the normalization field which is the gla ss-liquid transition field and that of the maximum pinning force are discus sed. The results suggest the existence of two phase structure in Bi-2223 an d Bi-2212 samples.
