摘要：
In this work, we synthesized epitaxial Y2NiMnO6 thin film by Pulsed Laser Deposition technique in two different atmospheres (oxygen and argon) and studied their magnetic as well as electric polarization. Room temperature ferromagnetism and ferroelectricity are exhibited by these Y2NiMnO6 thin films, indicating the coexistence of more than one ferroic interaction in this system. Here the surface roughness increases the total surface area and hence the unsaturated surface spins of the films which control both the ferromagnetic as well as ferroelectric order.
