On the critical behaviour of random anisotropy magnets
The effect of a local anisotropy of random orientation on a ferromagnetic phase transition is studied. To this end, a model of a random anisotropy magnet is analysed by means of a field theoretical renormalization group approach. The one-loop result of Aharony about the absence of a 2nd order ph...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The effect of a local anisotropy of random orientation on a ferromagnetic
phase transition is studied. To this end, a model of a random anisotropy
magnet is analysed by means of a field theoretical renormalization group
approach. The one-loop result of Aharony about the absence of a 2nd order
phase transition for isotropic distribution of random anisotropy axis at space
dimension d < 4 is corroborated. |
