| Abstract: | In this paper, we present a model of 2-D RICKY spin glass with nm1/21<<1, nm beins the magnetic impurity concertration and 1 the mean free path (this corresponds to a large concertration of nonmagnetic defects). The specific heat and the magnetic susceptibility at low and high temperatures are calculated. The percolation theory is applied to the transition region. The broad maximum of the specific heat and the "cusp" of the magnetic susceptibility are explained. |
