Low-temperature superconductivity is treated at an introductory level. The topics include Meissner-Ochsenfeld effect and London equations, thermodynamic properties of the superconducting state, type I and II superconductors, flux quantisation, superconductors in microwave fields and superconducting quantum interference effects. Important experiments are discussed. The basic ideas of the BCS theory and its implications are outlined.
Peter Schmueser (Sat,) studied this question.
