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 finitesize clusters. We observe that the transition temperature decreases with the strength of the randomness by diminution of the coherence of the itinerant electrons.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
