Phase transitions of 2D triangular antiferromagnetic Ising model in a uniform magnetic field near h=0 and T=0

Abstract

Using a microcanonical magnetization-energy (ME) diagram, this paper describes all the possible phase transitions of a 2D triangular antiferromagnetic (TAFM) Ising model in a uniform external magnetic field. In particular, we investigate the detailed phase boundary shape of the TAFM near h = 0 and T = 0 using staggered susceptibility. © Published under licence by IOP Publishing Ltd.
