Effect of Transition-Metal (Ni) on the Superconductor Y-Ba-Cu-O
Y-Ba-Ca-O 초전도체에서 천이금속(Ni)의 효과
Abstract
The X-ray diffraction pattern, electrical resistance, density and critical temperature of a series of YBa2(Cu3-xNix)O7-\ulcornersamples (0\ulcorner\ulcorner.5) were investigated with the increase of the Ni content. The samples show a principal 1.2.3-like phase with well resolved orthorhombic peaks. The final pattern of the x=0.1 sample appears to be well reacted orthorhombic YBa2(Cu,Ni)3O7-\ulcornerwith minor impurities and an appreciable amorphous fraction. From the above results, we conclude that Ni does not play an important role for the superconductivity in the Y-Ba-Cu-O system.
