| Outline of Research at the Start |
Nowadays, the question of how, and how fast, magnetization can be reversed is attracting great practical interest in hard disk drive (HDD) community. The applicant here unprecedently utilizes the interconversion between heat (phononic), light (photonic), and spin (spintronic) for ultrafast manipulation of magnetization reversal. Success of this proposal will bring revolutionary impact on the next-generation HDD with much higher recording areal density and energy efficiency.
