Amorphous magnetooptical recording material

Abstract

Abstract A magnetooptical recording material having improved stability to environmental influences has the form of an amorphous film and possesses an axis of easy magnetisation at right angles to the film surface. The recording material consists of a rare earth/transition metal alloy which contains Fe and Co, at least one element from the group Gd and Tb and a further element, such as 0.7 to 5 atom per cent of Pt or 1 to 10 atom percent of Se. The improved stability is achieved without any adverse effect on the magnetic or other physical properties of the recording material.
