This textbook provides a comprehensive introduction to the phenomenological theories of
superconductivity. Much emphasis is placed on a thorough development of theoretical approaches
to understand the basic properties of superconductors and their most important applications.
The content ranges from an overview of important experimental properties to the detailed
description of the London theory and the Ginzburg-Landau theory. Prominent effects like the
Meissner effect critical magnetic fields formation of vortices and many other phenomena are
theoretically explained in great detail.
