GROWTH AND CHARACTERISATION OF Bi₂Sr₂Ca₁Cu_2−xNi_xO_y SINGLE CRYSTALS

Abstract

Effect of partial substitution of Ni in the high T c superconductor single crystals Bi-Sr-Ca-Cu-O has been studied. Single crystals of Bi-Sr-Ca-Cu/Ni-O are grown from its stoichiometric melt. The addition of Nickel in this system ( Bi 2 Sr 2 Ca 1 Cu 2−x Ni x O y , x=0.1, 0.3) is found to change the growth temperature, superconducting transition temperature, surface morphology, and mechanical property.
