In the present paper the magnetic permeability μ, magnetic after-effects Δμ/μ, saturation magnetization μ0MS, Curie temperature TC, primary
crystallization temperature TX1
and magnetostriction coefficients λ were examined for a group of amorphous alloys, i.e. Fe80Si6B14 and Fe75XSi6B14
(X = Mo5, Mo2.5Mn2.5, Mo2.5Co2.5).
It was shown that these alloying additions cause a decrease of the Curie
temperature, saturation magnetization, magnetic permeability, magnetic
after-effects and magnetostriction coefficients, and
an increase of the primary crystallization temperature with respect to Fe80Si6B14.
The observed decrease of both magnetostriction
coefficients – saturation magnetostriction and volume
magnetostriction, is correlated with the decrease of
the Curie temperature. Cobalt and manganese atoms influence the crystallization
temperature in the same way as molybdenum, which means that the diffusion
processes responsible for crystallization are not enough sensitive to this kind
of alloying addition.
