Universality of phase transitions of frustrated antiferromagnets
Universality of phase transitions of frustrated antiferromagnets
Recent theoretical and experimental studies on the critical properties of frustrated antiferromagnets with non-collinear spin order, including stacked-triangular antiferromagnets and helimagnets, are reviewed. Particular emphasis is put on the novel critical and multicritical behaviours exhibited by these magnets, together with the important role played by the `chirality'.
