| Research Abstract |
Oxide materials exhibiting simultaneously magnetic and dielectric properties have been investigated. These potentially allow us to control the magnetic properties of magnetic materials which is a core in industry, using not magnetic but electric field. By this experimental study, preparation conditions of novel materials showing magnetism and dielectric properties at room temperature was found and thin films of new two type materials were successfully grown as candidates promising control of magnetic properties using electric field. It was also shown that piezoelectricity may be available to the control of magnetic characteristics of materials with a large magnetic anisotropy.
