| Research Abstract |
“Multifunctionality” is one of the key words in recent electrical industry. If we have four-state computer memories or the memories with the function of transistor, we could have smaller computers. In order to create the new multifunctional devices, developing new functionality in materials is recent trend in material science field. We have developed new functionalities in rare earth iron garnet films and epitaxial growth of non-garnet films on garnet substrates. Nowadays, rare earth iron garnets are well known as the materials exhibit large Verdet constants and ferrimagnetism. Because of their large magneto-optical properties in infrared light region, iron garnets are utilized as optical isolators. If we could develop a new property in rare earth iron garnet, the optical isolators may have a new functionality such as enhancement of Faraday rotation with applying an electrical field.
