摘要
The magnetic properties of bond-diluted nearest-neighbor interaction mixed spin-1/2 and spin-1 Ising ferrimagnetic spin system with different transverse fields are investigated within the framework of the finite cluster approximation (FCA). Particular emphasis is given to the square lattice with coordination number Z = 4 for which magnetizations are obtained. The interactions J(ij) are assumed to be independent random variable with distribution P(J(ij)) = p delta(J(ij) - J)+(1-p)delta(J(ij)), where J < 0. If bond concentration p varies in the certain ranges, we find that the compensation temperature is obtained for the values of the different transverse fields Omega(1/2) and Omega(1) in a restricted region. We obtain the values of the critical different transverse fields and critical bond concentration in this paper.
