Abstract
A spin model which displays inverse glass transition and inverse melting was investigated. It was observed that the strong degeneracy of the interacting states of an individual spin leads to entropic preference of the ferromagnetic phase, while lower energy associated with the noninteracting model yields a paramagnetic phase as temperature decreases. The model was found into the 'frozen' phase either by increasing temperature or by increasing the interaction strength which favour the entropic and interacting states. The results show that the qualitative features of this model resemble a large scale of inverse melting phenomena.
