Studies On Superconductor Nano Composite Of Bi2Sr2CaCu2O8/BiFeO3

Abstract

The phenomena of superconductivity are low temperature business. The low temperature works started with liquefaction of natural gases in the late 1800. Successful liquefaction of O2 was done by French scientist Caillettet in 1877. In 1911, superconductivity was discovered in
mercury at liquid Helium temperature by Dutch physicists H. K. Onnes [1]. He was awarded with Nobel prize for his work. Since its discovery in 1911, even today, superconductivity is an important area of research in solid state physics. The disappearance of resistivity in a material is called superconductivity, and the temperature at which it occurs is called as critical temperature (TC). The discovery of superconductivity opened a new area for research.
