UNSPECIFIED (1997) Triangular antiferromagnets. CANADIAN JOURNAL OF PHYSICS, 75 (9). pp. 605-655. ISSN 0008-4204Full text not available from this repository.
In this article we review the effects of magnetic frustration in the stacked triangular lattice. Frustration increases the degeneracy of the ground state, giving rise to different physics. In particular it leads to unique phase diagrams with multicritical points and novel critical phenomena. We describe the confrontation of theory and experiment for a number of systems with differing magnetic Hamiltonians; Heisenberg, Heisenberg with easy-axis anisotropy, Heisenberg with easy-plane anisotropy, Ising, and singlet ground state. Interestingly each leads to different magnetic properties and phase diagrams. We also describe the effects of ferromagnetic, rather than antiferromagnetic, stacking and of small distortions of the triangular lattice.
