Universality of phase transitions of frustrated antiferromagnets

Abstract

Recent theoretical and experimental studies on the critical properties of\nfrustrated antiferromagnets with the noncollinear spin order, including\nstacked-triangular antiferromagnets and helimagnets, are reviewed. Particular\nemphasis is put on the novel critical and multicritical behaviors exhibited by\nthese magnets, together with an important role played by the `chirality'.\n
