Unfolding of phases and multicritical points in the Classical Anisotropic van Hemmen Spin Glass Model with Random Field

S. G. Magalhaes, I. C. Berger, R. Erichsen

We study magnetic properties of the 3-state spin ($S_i=0$ and $\pm 1$) spin glass (SG) van Hemmen model with ferromagnetic interaction $J_0$ under a random field (RF). The RF fol…
