MAGNETIC MOMENT OF AMORPHOUS CoP ALLOYS

The temperature dependence of the saturation magnetization of amorphousCo_(100-x)P_x (x=13.9-27.7) alloys prepared by electrodeposition was measured by amagnetic balance in the field 12 kOe between 77 and 1300K. The average magneticmoment per Co atom, from low temperature measurements, decreases withthe increase of P content. The effect of P cothent on 3d magnetic moment in Coatom was discussed on the basis of the electron transfer model and the change ofcoordination number of nearest-neighbour Co atom around the central Co atom.
