    • A thin film of an amorphous alloy comprising (i) at least one element selected from Fe and Co, (ii) at least one element selected from Pt and Pd and (iii) at least one element selected from (a) 3d transition elements other than Fe and Co, (b) 4d transition elements other than Pd, (c)5d transition elements other than Pt, (d) light rare earth elements, (e)Group III B elements, (f)Group IV B elements, (g)Group V B elements, and (h)Group VI B elements, and the film having an easy axis of magnetization perpendicular to the film face. The thin film has excellent magnetooptical characteristics including increased coercive force and large Kerr-rotation angle and Faraday-rotation angle, and is excellent in resistance to oxidation and In consequence the coercive force and Kerr-angle of the film do not substantially change with time. The film has a high reflectance as well.
    • 一种非晶合金薄膜,其包括(i)至少一种选自Fe和Co的元素,(ii)至少一种选自Pt和Pd的元素和(iii)至少一种选自(a)3d过渡元素的元素 (b)除Pd以外的4d过渡元素,(c)除Pt以外的5d过渡元素,(d)轻稀土元素,(e)III族B元素,(f)IV族元素,( g)VB族元素,(h)VIB族元素,和具有与膜面垂直的易磁化轴的膜。 该薄膜具有优异的磁光特性,包括矫顽力增大和克尔旋转角度和法拉第旋转角度,耐氧化性优异,因此膜的矫顽力和克尔角基本上不随时间而变化。 该膜也具有高反射率。
