The content of the lecture includes the following topics:

- Basics properties of superconductors and superconducting materials (different types of superconducting materials, superconductors in a magnetic field, type-I and type-II superconductors, thermodynamic properties)

- Phenomenological description of superconductivity (London theory, superconductivity as a macroscopic quantum phenomenon, Ginzburg-Landau theory)

- Flux quantization, Josephson effects

- Overview over microscopic BCS theory

- Critical currents

- Application of superconductivity

- Unconventional superconductors (e.g. cuprates, iron-pnictides)
