Exchange coupled composite FePt/TbCo/[Co/Ni]N films with an TbCo interlayer
Source abstract
Abstract
The exchange coupled composite FePt/TbCo/[Co/Ni]N films have been prepared by DC magnetron sputtering. The net magnetization of ferromagnetic TbCo changes with the temperature variation, and then the magnetic configuration of FePt/TbCo/[Co/Ni]N changes. When a RE-dominated Tb32Co68 is inserted, FePt/Tb32Co68/[Co/Ni]5 has high coercivity at room temperature because of its synthesis ferrimagnetic sandwich structure, but small coercivity is obtained when the temperature is higher than 200 °C because of its graded ECC structure.
