A Search for a Low Anisotropic Superconductor

Abstract

In this article, we have given a review of thallium based (TlmBa2Can-1CunO2n+2) and copper based (CuBa2Can-1 CunO2n+4) high temperature superconductors. This review article is based on the methods of preparation in the form of bulk and thin films and their physical properties. We have also studied the sources of anisotropy and methods of lowering it via changing the composition of charge reservoir layer and developing a better inter-plane coupling.
