Tricriticality and Reentrance in a Naive Spin-Glass Model
arXiv:1005.3334 · doi:10.1103/PhysRevB.82.052402
Abstract
In this paper a spin-1 spin-glass model under the presence of a uniform crystal field is investigated. It is shown that the model presents both continuous and first-order phase transition separated by a tricritical point. The phase diagram is obtained within the replica-symmetric solution and exhibits reentrance phenomena at low temperatures. Possibly it is the simplest model which can describe inverse freezing phenomena.
