Abstract:

Fe¬5GeTe2(이하 F5GT)은 2차원 자성체 중에 가장 높은 큐리온도(~320 K)를 가지고 있는 물질 중 하나로, 최근 연구가 많이 되고 있다. 본 발표에서는 크게 두가지 주제에 대해서 다룰 예정이다. 첫번째는 F5GT의 온도에 따른 자성특성, 두번째는 저온에서 발현되는 수송현상 관련 연구결과이다. 첫번째 주제의 경우, 이 연구를 통해 약 270 K에서 F5GT가 나선형 자성 특성을 갖게 되며, 이는 결정 비대칭구조에 의한 쟐로우신스키-모리야 상호작용에 의한 것임을 주사 터널 현미경 측정을 통해 증명할 예정이다. 두번째 주제에서는 F5GT가 전류밀도에 따라 자기 저항의 크기가 바뀌고, 이것이 자기상변화와 관련되어 있음을 논의할 예정이다.
