The magnetic properties of melt-spun(Fe_(1-x)Nd_(x))_(94)B_(6) alloys(x=0.07-0.90)are reported.Their spontaneous magnetizations are interpreted on the basis of a sperimagnetic structure with Nd and Fe cones.The highest coercivity at room temperature is 8 kOe for this as-quenched amorphous alloy system.
