Multifunctional Materials Science: An Experimental Study

One particular obstacle to the development of these materials is that the coexistence of ferromagnetic and ferroelectric properties is normally contra-indicated. Further studies are required to understand the microscopic mechanism producing this coexistence and coupling between typically mutually exclusive ferroic order parameters.Magneto electric multiferroics provide an important advantage in designing new devices, due to the control of magnetic order using electric field. This may lead to the development of a new class of spin based electronics, magnetic sensors, transducers, and attenuators. These technological benefits have made magneto electric multiferroics a very active area of research and have spurred the search and design of new multiferroic materials. The recently revived interest in a different class of multifunctional materials, in which two or more ferroic properties, being ferro or antiferroelectricity, ferro or ant ferromagnetism and ferro or antiferroelectricity coexist in what are known as multiferroic materials is driven both by the potential applications of these systems as well as a desire to more deeply understand the physics underlying this behavior. Among these multiferroic materials, those displaying anti/ferromagnetic and anti/ferroelectric properties are known as magneto electric multiferroics
