Piezomagnetic Piezoelectric Composite Material and Its Applications

The Magnetic materials which have combined electrical and magnetic properties are known as piezomagnetic material (ferrites). Iron oxide and metal oxides are the main constituents of the ferrites. The importance of ferrite material has been known to mankind for many centuries, Piezoelectric are the polar materials, which can spontaneous, reversible electric polarization, which can be reversed by applying suitable electric field. A composite material is made by combining two or more dissimilar materials. They are combined in such a way that the resulting composite material or composite possesses superior properties .which are not obtainable with a single constituent material. So, in technical terms, we can define a composite as 'a multiphase material from a combination of materials, differing in composition or form, which remain bonded together, but retain their identities and properties, without going into any chemical reactions.' The components do not dissolve or completely merge. They maintain an interface between each other and in concert to provide improved.
