“…Today the majority of the amorphous alloys including rare-earth elements is recognized to be random anisotropy magnets. This class of amorphous materials includes binary alloys [8,9,10,11,12,13,14], alloys of rare earths with two metallic components [15,16,17,18,19,20,21,22,23,24], alloys of rare earth with a metal and a non-metallic component [25,26,27,28,29] and multicomponent alloys [30,31,32,33,34,35]. The structure of these compounds is characterized by an uniform (isotropic) distribution of the direction of the random anisotropy axes.…”

The problem of critical behaviour of three dimensional random anisotropy magnets, which constitute a wide class of disordered magnets is considered. Previous results obtained in experiments, by Monte Carlo simulations and within different theoretical approaches give evidence for a second order phase transition for anisotropic distributions of the local anisotropy axes, while for the case of isotropic distribution such transition is absent. This outcome is described by renormalization group in its field theoretical variant on the basis of the random anisotropy model. Considerable attention is paid to the investigation of the effective critical behaviour which explains the observation of different behaviour in the same universality class.Comment: 41 pages, 10 figure
