On the exact solution of the mixed-spin Ising chain with axial and rhombic zero-field splitting parameters
arXiv:1102.0846
Abstract
Ground-state phase diagram of the mixed spin-$1/2$ and spin-$1$ Ising chain with axial and rhombic zero-field splitting parameters is exactly calculated within the framework of the transfer-matrix method. It is shown that the rhombic zero-field splitting parameter prefers the magnetically ordered phase instead of the disordered phase.
