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. The phase diagrams in the longitudinal field-temperature plane and in the transverse field-temperature plane are determined, respectively. The results show that the tricritical points can occur in a certain 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.
