چکیده انگلیسی
Ferroelectromagnet is a special compound which shows the coexistence of the spontaneous ferroelectricity and (anti)ferromagnetism in the same phase. The inherent magnetoelectric (ME) coupling effect is the most attractive property for the ferroelectromagnetic compound. In this paper, we thoroughly research into the influence of the inherent ME coupling on the properties of the three-dimensional ferroelectromagnetic system, including the magnetization, magnetic susceptibility, polarization and dielectric susceptibility. Calculation reveals that the magnetic and dielectric properties both display some anomalous change for the influence of the ME effect. For dielectric properties, an anomaly in both spontaneous polarization and dielectric susceptibility is observed, indicating the onset of the magnetic order. For magnetic properties, an excursion in Néel temperature TN is observed, indicating the influence of the ferroelectric order. In addition, the ME-coupling dependence of the spin wave excitations of the three-dimensional ferroelectromagnetic system is also considered.
