Sm/sub 2/(Co,Fe,Cu,Zr)/sub 17/ magnets with higher Fe content

The magnetic properties of Sm/sub 2/(Co,Fe,Cu,Zr)/sub 17/ magnets were improved by increasing the Fe content without raising the Zr content. With increasing Fe content, the remanence rises monotonically while the intrinsic coercive force drops sharply for 0.27>
