| Research Abstract |
This work is a study on magnetic recording materials used in hard disk drives. The fabrication of current recording media needs ruthenium as underlayers in order to control the growth and properties of the magnetic layers. However, ruthenium is a noble metal that is being rapidly consumed. Therefore, development of ruthenium-free recording media is necessary. In this work aluminum nitride has been used to control the growth and properties of CoPt layers, and perpendicular magnetic anisotropy, which is necessary for magnetic recording, has been successfully realized.
