| 中文摘要 | A two-sublattice Ising metamagnet in both external longitudinal and transverse fields is studied within the mean-field approach based on Bogoliubov's inequality for the Gibbs free energy. At finite temperatures, by changing values of the parameters of the model many different types of phase diagrams in the longitudinal field-temperature plane and in the transverse field-temperature plane are determined. The results show that the tricritical point can occur and decomposes into a critical end point and a double critical end point in a certain small region of the external longitudinal and transverse fields. The temperature of the tricritical point monotonically increases with decreasing the transverse magnetic field Omega and increasing the longitudinal magnetic field h. A line of fourth-order critical points is also determined. |
