Abstract

A review of Landau's theory of second order phase transitions is given with special emphasis on its application to determine the possible magnetic structures that can arise when a paramagnetic crystal undergoes a magnetic phase transition. Using group theoretical methods the restrictions for the change of the magnetic symmetry are outlined. It is shown that for not too complicated magnetic structures the symmetry can be determined without group theoretical calculations. Second order phase transitions between two magnetic phases are also discussed.
