초록

한 고체의 자성은 원자가 전자의 양자역학적 상태에 의해 결정되는데, 스핀편극 각도분해 광전자 분광학(SP-ARPES)은 고체안의 전자상태를 조사할 수 있는 가장 강력한 방법으로 어떤 물질의 자성을 이해하는 데에 많은 도움을 준다. 본고에서는 SP-ARPES 방법에 대한 간락한 소개와 이를 통해 얻을 수 있는 물리적 정보에 대해 기술한다.

Magnetic properties of a solid are determined by the quantum mechanical states of valence electrons. Spin-polarized angle-resolved photoemission spectroscopy (SP-ARPES) is a powerful tool to probe the electronic states in a solid and provides valuable information on magnetic properties of a solid. In this article, brief introduction to SP-ARPES and its applications are provided.
