Amorphization of a crystalline diluted Ising ferromagnet

Abstract

The amorphization of a diluted Ising ferromagnet on a square lattice is investigated with the use of a new type of effective-field theory with correlation. The exchange parameters are assumed to be distributed according to a $\ensuremath{\delta}$ function. The transition temperature, phase diagram, magnetization, and susceptibility are evaluated. We find some characteristic behavior for the amorphization.
