✦ Synopsis

We have studied a infinite-range planar XY model in the presence of a random field. We have analyzed the dynamics of the system through a Fokker-Planck formalism, focussing our attention in the long time behaviour. This technique allows to compute exactly the phase diagram of the model.

The phase diagrams of a random-bond mixed spin Ising system consisting of spin-~ and spin-I wtth a transverse field are investigated within the framework of an effective-field approximation. Our phase diagram of zero transverse field is completely equivalent to that based on the finite cluster appro
