초록

자기변형(magnetostriction) 현상은 외부 온도와 자기장이 변할 때 자성체의 모양이나 부피가 변하는 현상이다. 반강자성을 갖는 희토류 원소와 화합물에서의 관측되는 자기변형 현상은 결정장에 의한 결정장 변형(crystal-field striction)과 교환상호작용에 의한 교환 변형(exchange striction)으로 잘 설명할 수 있음이 알려져 있다. 이 해설 논문에서는 결정장과 교환 상호작용을 포함하는 자기변형 표준이론에 대하여 논의하고자 한다.

The phenomenon of magnetostriction occurs in magnetic systems when the temperature is changed or the external magnetic field is applied. It is known that the magnetostriction observed in rare-earth elements and compounds is well described by the crystal-field striction and the exchange striction. In this review paper, we discuss the standard theory for the magnetostriction which includes the crystal-field and the exchange interaction.
