Abstract

We investigated the changes of the magnetic properties in electroplated Permalloy thin films by a few organic additives added to the plating electrolytes. Under identical electroplating conditions, the crystalline orientations and the surface roughness of the plated thin films were different from those prepared with a pure electrolyte. These property changes reduced the coercivity and increased the magnetoimpedance ratio (MIR) up to 20%.

퍼말로이 도금용 순수전해액에 유기첨가제(organic additive)를 첨가하여 제작된 박막의 물성과 자성의 변화를 조사하였다. 일정한 도금조건에서 특정한 유기첨가제를 첨가하여 도금한 퍼말로이 박막은 순수한 전해액으로만 제작된 박막과는 결정성과 표면 거칠기가 달라진다. 그 결과로 도금 박막의 보자력 등 자기적 특성이 변화하였다. 유기첨가제에 의한 이러한 특성 변화는 자기임피던스 비율을 최대 20%까지 증가시키는 역할을 하였다.
