The magnetic susceptibility on the transverse antiferromagnetic Ising model: Analysis of the reentrant behaviour

We study the three-dimensional antiferromagnetic Ising model in both uniform longitudinal ($H$) and transverse ($Ω$) magnetic fields by using the effective-field theory with finite cluster $N=1$ spin (EFT-1). We analyzed the behavior of the magnetic susceptibility to investigate the reentrant phenomena we have seen the same phase diagram previously obtained in another papers. Our results shows the presence of two divergences in the susceptibility that indicates the existence of a reentrant behaviour.
