Electrical and Magnetic Properties in Bi₂Sr₂Ca_1-xY_xCu₂O_8+δ

Abstract

Electrical and magnetic properties were examined on Bi 2 Sr 2 Ca 1- x Y x Cu 2 O 8+δ . A solid solution was confirmed in this system for x between 0 and 1. With increasing Y, the superconducting transition shifted toward lower temperatures, and a transition to an antiferromagnetic insulator was observed. Since the oxygen content was not influenced by Y substitution, the decrease in T c and the transition to AFI seemed to be attributed to the decrease in the hole concentration in the Cu-O level.
