Abstract

Hall coefficients of superconducting YBa₂Cu₃O _y/Nd_0.7Sr_0.3MnO₃ (YBCO/NSMO) multilayers were measured to investigate the effect of flux pinning on the Hall behavior. The lower pinning ability accompanying a diminishing sign reversal of Hall coefficient is due to a decrease of flux pinning in YBCO/NSMO multilayers. The volume pinning force, F_p= -J_c × H, of YBCO/NSMO multilayers can be represented as F_p ∞ (H/H_c2) ^0.5(1 - H/H_c2)². This suggests the existence of two-dimensional pinning centers in measured samples. The Hall coefficient and pinning force of (YBCO/NSMO) multilayers are compared with data of YBa ₂Cu₃O_y/PrBa₂ Cu₃ O _y superlattices.
