Abstract

SQUID studies of magnetic relaxation and hysteresis on a zone-melted YBa2Cu3O(6+x) sample suggest a nonlogarithmic magnetization decay at high temperature, which can be attributed to a nonlinear U(J) relationship originating from the local pinning potential Up(x). The U(J) relationship helps determine the local pinning potential to be Up(x) = U0(x/x0)(1-ln(x/x0)).

Abstract

Magnetic hysteresis loops (MHLs) are comparatively measured on both textured and single crystalline [Sc.sub.5][Ir.sub.4][Si.sub.10] superconductors. Three kinds of peaks of the flux pinning force are observed at low fields near zero, intermediated fields, and high fields near the upper critical field.
