THERMODYNAMIC PROPERTIES OF INFINITE-RANGED RANDOM MAGNETIC SUSTEMS

We consider the Ising model in which the spins are coupled by infinite-ranged random interactions. These interactions are independently distributed with a Gaussian probability distribution. Both spin-glass (SG) and ferromagnetic (FM) systems occur. The coFinally, all the exact results obtained here for thermodynamic properties are compared with those of the earlier studies on the disordered magnetic systems. Our results are in complete agreement with many other Ising models in random field and spin glass
