Abstract
A review is given of our recent results on magnetically ordered states occuring in geometrically frustrated stacked triangular (simple hexagonal) antiferromagnets based on phenomenological Landau theory, molecular field theory, and Monte Carlo simulations. Novel multicritical behavior in magnetic field‐temperature phase diagrams is demonstrated for systems with axial and planar anisotropy (weak and strong). Crossover effects are discussed in terms of the new chiral universality classes recently proposed by Kawamura. Comparison of theory and simulation results with the observed magnetic ordering and phase diagrams in a wide variety of ABX 3 compounds is made.This publication has 37 references indexed in Scilit:
