Abstract

The article reviews recent developments on magnetic properties of superconductors with anisotropic Cooper pairing. In particular, we show how the concept of broken symmetries is applied to the investigation of the mixed state in superconductors with a multicomponent order parameter. Starting from the phenomenological description in the framework of the generalized Ginzburg-Landau theory, we discuss different types of quantized vortices appearing at Hc1H_{c1} in states with and without time-reversal breaking. General classification of superconducting phase transitions in a uniform magnetic field at Hc2H_{c2} is constructed. Vortex lattices of different forms are found in the vicinity of the upper critical field. Symmetry arguments are used to classify phase transitions inside the mixed state. Special attention is given to results which can be obtained analytically. Also special emphasis is put on the open questions of the theory.
