- The temperature and the field dependences of the magnetization have been measured for Fe73.5-xCrxCu1Nb3Si13.5B9 (0 < ;= x < ;= 17.5) prepared by using a melt spin technique. The temperature dependence of the magnetization in the range of 5 to 300 K with an applied field of I Tesla for all the compositions follows the relaxation M(T) = M-0(1 - BT3/2 - CT5/2), which is indicative of the presence of a spin wave excitation. The saturation magnetizations at 5 and 300 K decrease linearly with Cr concentration for the entire composition range, which indicates that a simple dilution of the Fe moment takes place due to Cr substitution. The field-cooled (FC) and the zero-field-cooled (ZFC) magnetizations measured with an applied field of 1 Oe show divergences for x = 10, 12.5, 15 and 17.5, which may be attributed to the magnetic hardening at low temperatures.
