摘要
The effects of magnetoresistance and magnetocapacitance in the ferromagnetic semiconducting compound of La2NiMnO6 near room temperature, were analyzed. The single-phase samples of La 2NiMnO6 were prepared using conventional solid-state synthetic methods. The magnetic susceptibility of this compound in an applied field of 1T shows a magnetic transition at ∼280 K, indicating the onset of ferromagnetic long-range ordering. The results show that the appearance of both magnetoresistance and magnetocapacitance effects in La2NiMnO 6 indicates coupling between the magnetic, electronic, and dielectric properties, which may be controlled by the application of magnetic fields.
