소둔 및 급속응고한 ?? 합금계의 자기적 성질

Abstract

소둔 및 급속응고한 ?? ?? 합금계의 결정구조및 자기적 성질을 비교 분석하였다.

x-선 회절실험 결과, 소둔시편은 x=0.05, 0.15, 0.20 및 0.25은 B2 구조를 띄며 x=0.10, 0.30, 0.35 및 0.40은 L2 구조를 띄고 있었다. 급속응고 시편은 x=0.05, 0.15, 0.20, 0.25, 0.30 및 0.35은 B2구조를 띄며 x-0.10와 0.40은 L2 구조를 띄었다.

자화측정 결과, 소둔시편은 x=0.05, 0.15 및 0.25은 상자성, x=0.10, 0.20, 0.30, 0.35와 0.40은 초상자성을 띄었다. 급속응고 시편은 0.05≤x≤0.15 잎때는 상자성, 그리고 0.20≤x≤0.40에서는 약한 초상자성을 나타내었다.

본 합금게의 자기적 특성을 국부환경 효과의 관점에서 분석하여 보았다.

Crystal structures and Magnetic properties on the annealed and rapidly solidified ?? alloy systems were investigated.

,From X-ray diffraction data, annealed specimens appeared to be B2 structure when 0.40. Rapidly solidified specimens appeared B2 structure when x=0.05, 0.15, 0.20, 0.25, 0.30, 0.35, L2 structure when x==0.10, 0.40.

From magnetic measurements, annealed specimens showed paramagnetism when x=0.05, 0.15, 0.25 and seemed to be superparamagnetism when x=0.10, 0.20, 0.30, 0.35, 0.40 at measured temperatures. Rapidly solidified specimens appeared paramagnetism when 0.05≤x≤0.15, weak superparamagnetism when 0.20≤x≤0.40.

The magnetic properties were analyzed on the point of view of the local environmental effect.
