摘要：
In this paper we study the impurity effect on magnetic and thermodynamic properties in double-exchange systems using the Monte Carlo calculation. We find the effect of randomness on ferromagnetic transitions and on the specific heat for finite-size clusters. We observe that the transition temperature decreases with the strength of the randomness by diminution of the coherence of the itinerant electrons.
