Using mean field approximation, we investigate the Blume-Capel model with random bond. The system is self-organized into blocks, which behave like superspins and are coupled with their neighbors. The methods to search the elementary blocks and calculate their coupling are proposed. For the strongly disordered case, the coupling distribution is exponential… CONTINUE READING
