| 中文摘要 | The ground state magnetic properties of a two-sublattice Ising metamegnet in both external longitudinal and transverse fields are studied within the mean-field approach. A parameter alpha = (Z(1)J(1) + Z(2)J(2))/(Z(1)J(1) - Z(1)J(1)) which reflects the strength ratio of spin coupling in the plane and in adjacent planes is introduced. The ground state energy, the longitudinal staggered magnetization, the longitudinal total magnetization and the transverse total magnetization are calculated. The ground state phase diagrams in Omega-h and Omega-alpha plane are presented. The results show that when Omega is given, the longitudinal critical magnetic field increases when alpha decreases; the phase transition changes always from first order to second order with increase in the longitudinal magnetic field h or decrease in alpha. The reentrant phenomenon occurs in the range alpha <=-0.66, Omega <= 0.21, h >= 0.78. (c) 2007 Elsevier B.V. All rights reserved. |
