1105889-A1 cites 1 patents.

Magnetic nanocomposite materials including iron, rare earth elements, boron, refractory metals and cobalt which have favorable magnetic properties and are suitable for making bonded magnets are disclosed. Compositions of the present invention can be of the formula: (Nd1-yLay)vFe100-v-w-x-zCowMzBx, where M is at least one refractory metal selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W; v is from about 5 to about 15; w is greater than or equal to 5; x is from about 9 to about 30; y is from about 0.05 to about 0.5; and z is from about 0.1 to about 5. Preferably M is at least Cr. These materials have good magnetic properties and are suitable for use in preparing bonded magnets.
