M. Konc et al., TEMPERATURE-DEPENDENCE OF THE MAGNETIZATION AND OF THE OTHER PHYSICAL-PROPERTIES OF RAPIDLY QUENCHED AMORPHOUS COB ALLOYS, IEEE transactions on magnetics, 30(2), 1994, pp. 524-526
We report here our results on magnetization study of amorphous Co100-x
Bx ribbons with 20 less-than-or-equal-to x less-than-or-equal-to 30 at
.% B in the temperature range 10K to 800K and in applied magnetic fiel
d 5-10(3) A/m. The thermomagnetization curve is round to obey the Bloc
h law, M(s)(T) = M(s)(0)(1-betaT3/2-gammaT5/2), spin wave stiffness co
nstant and the range of the exchange interaction were calculated from
the experimental results. We have found that the B content has a stron
g effect on stiffness constant D.
