Spin Reorientation and Dynamics in Nanoferromagnetic Thin Films
관련링크
본문
"Today we stand on the verge of a spintronics revolution, where spin-dependent new phenomena will be not only explained but exploited in novel devices. Thus, upcoming challenges in magnetism research include the manipulation of new magnetic materials and structures at the exchange-interaction scales and also, to understand and utilize the implication of the novel phenomena.
In this talk I will present the highlights of spin reorientation and spin dynamics phenomena in nanothin ferromagnetic systems discovered by means of in-situ submonolayer-sensitive vector magnetometry, a magneto-optical microscope magnetometer (MOMM) capable of grabbing domain reversal patterns in real time, a pump-probe Kerr microscopy enabling ultrafast spin dynamics study with 10 fs time resolution. In particular, the discussion will be focused on 2nd-order spin reorientation transition, reversible spin switching via magnetoelastic coupling, Barkhausen critical scaling behavior observed at 100 ms regime, and precessional motion of spins at sub-ns regime.
