ABSTRACT:
a 바카라 배팅 법tronics revolution, where 바카라 배팅 법-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 바카라 배팅 법 reorientation and 바카라 배팅 법 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 바카라 배팅 법 dynamics study with 10 fs time resolution. In
particular, the discussion will be focused on 2nd-order 바카라 배팅 법 reorientation
transition, reversible 바카라 배팅 법 switching via magnetoelastic coupling, Barkhausen
critical scaling behavior observed at 100 ms regime, and precessional motion of
바카라 배팅 법s at sub-ns regime.
