Superconductivity is an important field in the low temperature Physics. Anisotropy in superconductors plays an important role for the observation of the materials. Ginzburg-Landau Theory has good significant during understanding the high temperature superconductors.The main subject of the book is to understand the Phenomenological GL-Theory an different high temperature superconductors theoretically.

Superconductivity is a phenomenon in certain materials at extremely low temperatures, characterized by exactly zero electrical resistance. It is an important field in the low temperature physics. Study of anisotropy plays an important role for different superconducting materials. In view of this, Ginzburg-Landau (GL) theory is an important tool for understanding the high temperature superconductors. In this book an attempt has been made to study the anisotropy arising in copper dopped titanium diselenide superconductor through Phenomenological GL-theory.
