Abstract Experimental results for atomic magnetic moment,Curie temperature,T_C,andcoefficient B of the T~(3/2)term in the Bloch law for amorphous alloys Fe-M-B(M=Cr,Mo or W)prepared by the drum spinning technique are reported.Theaverage magnetic moment for each metal atom is 2.0,-3.96,-4.62 or -4.08μ_B for Fe,Cr,Mo or W respectively in the three amorphous alloy systems.Thedecrease of T_C is at the rate of 20.5K/at.-% Cr,27.7K/at.-% Mo,or 26K/at.-%W with increasing Cr,Mo or W content respectively.These results are discussedin the light of a‘mixed’model due to C.W.Chen.The effect of the magneticshort range order around T_C is clearly observed by applying an external magneticfield.The coefficient B increases with the concentration of Cr,Mo or W,whichis interpreted as a consequence of weakening of exchange coupling between themagnetic atoms.
