Title: | INVESTIGATIONS OF DOPED L10 FEPT FILMS FOR HEAT ASSISTED MAGNETIC RECORDING (HAMR) | Authors: | XU DONGBIN | Keywords: | FePt, HAMR, L10, Doping, Temperature, Synchrotron radiation | Issue Date: | 18-Feb-2013 | Citation: | XU DONGBIN (2013-02-18). INVESTIGATIONS OF DOPED L10 FEPT FILMS FOR HEAT ASSISTED MAGNETIC RECORDING (HAMR). ScholarBank@NUS Repository. | Abstract: | L10 FePt with high magnetic anisotropy possesses the most promising role to realize the potential of heat assisted magnetic recording (HAMR) for ultra-high density recording. The issues of degradation and thermal design brought by the integration of thermal dimension in the writing process make the thermal investigation of L10 FePt HAMR media highly desirable. This thesis mainly focused on investigating the thermal-dependent structural and magnetic properties of L10 FePt using different doping elements. The doping effects and the relations between macroscopic properties (crystallographic structure, magnetic properties and their thermal dependences) and microscopic properties (local atomic structure and spin/orbital moments) were studied. An in-depth investigation on the effects of composition, heat sink layer and doping elements including Nd (rare-earth), Mn (3d-transition) and Rh (4d-transition) on the structural properties, magnetic properties and their thermal dependences of L10 FePt was pursued. | URI: | http://scholarbank.nus.edu.sg/handle/10635/47547 |
