Abstract

본 발명은 광자기 기록재료용 합금의 제조방법에관한 것으로서 철, 테르븀 및 보론을 적절한 비율로 조성하고 그 조직이 비정질이 되도록 함으로써 자기보상점이 상온부근에 존재하는 인성이 우수한 광자기기록 자성재료용 비정질 합금의 제조방법을 제공하고자 하는데 그 목적이 있다.The present invention relates to a method for manufacturing an alloy for a magneto-optical recording material. The composition of iron, terbium, and boron in an appropriate ratio, and the structure thereof to be amorphous so that the magnetic compensation point is near the room temperature, the magneto-optical recording material for excellent magnetic properties It is an object of the present invention to provide a method for producing an amorphous alloy.

본 발명은 원자%로 50-70%의 Fe, 15-25%의 Tb, 및 잔부 B으로 조성된 합금을 용해한 후, 비정질 조직을 갖도록 임계 냉각속도 106°K/S 이상으로 급냉하는 것을 특징으로 하는 인성이 우수한 광자기 기록자성재료용 합금을 제조하는 방법에 관한 것을 그 요지로 한다.The present invention is characterized by dissolving an alloy composed of 50-70% Fe, 15-25% Tb, and the balance B in atomic%, and then quenched at a critical cooling rate of 10 6 ° K / S or more to have an amorphous structure. The summary relates to a method for producing an alloy for magneto-optical recording magnetic materials having excellent toughness.

본 발명은 자기보상점이 상온부근에 존재하고 인성이 뛰어난 광자기 기록재료로 폭넓게 사용될 수 있는 큰 효과가 있다.The present invention has a great effect that the magnetic compensation point can be widely used as a magneto-optical recording material excellent in toughness and present near room temperature.
