Diamagnetic Properties of High-Tc Bi-Sr-Ca-Cu-O Superconducting Thin Films
Abstract
The diamagnetic properties of superconductive Bi-Sr-Ca-Cu oxide thin films were studied, by using an rf SQUID susceptometer. The specimen showing diamagnetization up to about 100 K has also indicated the zero-resistance temperature of 102 K. The critical current density is estimated from the diamagnetization shielding effect to be 3.3× 106 A/cm2 at 4.2 K and 7× 104 A/cm2 at 77 K.
