Abstract

The antiferromagnetic (AF) Ising model on a stacked triangular lattice (a hexagonal loose packed one) has been of considerable interest as a model of compound CsCoCI3 which exhibits extraordinary phase transitions, but not well elucidated yet[1]. In the triangular layers besides AF couplings between nearest neighbors (nn) −J 1 (<0), it has ferromagnetic (F) couplings J 2 between next nn, and F couplings J 0 between the layers. In this article we briefly give preliminary results and further study will be given elsewhere.
