Spin glass with short-range action in the vicinity of the "transition"
The behavior of spin glass with nonmagnetic defects in the vicinity of the percolation threshold in a finite magnetic field (h) is analyzed by percolation-theory methods. It is shown that the heat-capacity increment AC(h)— C(/z)-C(0) and the magnetic susceptibility дМ/dh are directly connected with the cluster dimension distribution function. Power-law dependences on h and (Γ-Θ)/Θ are obtained on the basis of similarity theory.
