Double perovskite Y2NiMnO6 nanowires: high temperature ferromagnetic–ferroelectric multiferroic

Abstract

This work demonstrates the unusual room temperature ferromagnetism and ferroelectricity of the double perovskite multiferroic Y2NiMnO6 nanowires, fabricated using a facile solvothermal route. The physics behind the co-existence and coupling of ferroelectricity and ferromagnetism in Y2NiMnO6 nanowires at high temperature is the key focus of this article. The studies indicate that the large concentration of surface spin and the surface charge polarization associated with the surface electrons of the unique one dimensional high aspect ratio nanowires are responsible for the ferromagnetism and ferroelectricity, respectively at room temperature. It is believed that the ferromagnetism and ferroelectricity are mutually coupled with each other and they have a similar origin.
