Abstract
The results of a detailed histogram Monte Carlo study of critical-fluc tuation effects on the magnetic-field temperature phase associated wit h the hexagonal Heisenberg antiferromagnetic with weak axial ansiotrop y are reported. The multipahse point where three lines of continous tr ansitions merge at the spin-flop boundary exhibits a structure consist ent with scaling theory but without the usual umbilicus as found in th e case of a bicritical point.
