초록

니켈-철 합금 박막의 성분을 연속적으로 변화시키는 방법을 조사하였다. 일정한 전해액에 가해지는 도금 전류와 전압의 변화에 따라 박막 내 니켈과 철의 상대적 함유량의 조절이 가능했는데, 그 결과 도금 박막의 보자력, 각형비 및 포화자기장이 변화하였다. 정전류도금과 정전압 도금 방법으로 박막 내 철의 함유량을 증가시킴에 따라 박막의 입도는 증가하였고 보자력은 감소하는 경향을 나타내었다.

We have studied a means to control the composition of nickel-iron thin films. By changing current and voltage applied to a electroplating electrolyte we could manipulate the relative concentration of nickel and iron in the thin films, which caused variations of coercivity, squareness, and saturation magnetic field. As we increase the content of iron in the thin films by using potentiostatic and galvanostatic plating, the grain size was increased and the coercivity was reduced.
