Abstract

Electrical resistivity of Co₄₈Fe₂₅Si₄B₁₉Nb₄ amorphous alloy and with small additions of rare-earth metals (= Nd, Sm, Tb, Yb) was studied using the AC four-probe method. It was found that these alloys have a specific behavior of electrical resistivity after crystallization-temperature dependences of resistivity at cooling are non-linear and can be fitted as ln R ~ T^−1/4.
