| Outline of Final Research Achievements |
A rare earth-transition metal amorphous alloy film is a system known as a material of a magnetic recording material. In this study, the spin and orbital specified magnetization curves, and as well as, element specified magnetization curves of Tb x Co 100 - x films were measured by combing total magnetization curve measurement and magnetic Compton scattering measurement. The spin magnetic moment, the orbital magnetic moment, the Tb magnetic moment and the Co magnetic moment direction are reversed with the magnetic compensation composition around x=17. Since the 4f orbital of rare earth Tb is dominant and the system with large spin orbital interaction is used in the system used in this study, the ratio of spin to orbit, the ratio of Tb and Co is nearly constant. It is consistent with the theory of rectangular exchange interaction.
