Relationship between the Crystallinity and Magnetic Properties of Cr2O3/LiNbO3/Cr2O3 Multi-Layer Materials
The magnetic properties of an artificial multiferroic material, a Cr2O3/LiNbO3/Cr2O3 hetero structure with various-thickness LiNbO3 layers, were investigated. All samples showed ferromagnetism due to the existence of oxygen deficiency or an excess of the Cr2O3 layer in the LNO/Cr2O3 interface. The ferromagnetism of the samples was affected by the crystal orientation of the LiNbO3 layer, and seemed to have a major impact on the magneto-electric behavior of this hetero system.
