Abstract: Electrical resistivity of Co$_{48}$Fe$_{25}$Si$_4$B$_{19}$Nb$_4$ amorphous alloy and with small additions of rare-earth metals (R= 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 $\ln R\sim T^{-1/4}$.

Keywords: amorphous alloys, metallic glasses, electrical resistivity, rare-earth metals.
