Electrical resistivity of Co 48 Fe 25 Si 4 B 19 Nb amorphous alloy and with small additions rare-earth metals ( = Nd, Sm, Tb, Yb) was studied using the AC four-probe method. It found that these alloys have a specific behavior electrical after crystallization-temperature dependences at cooling are non-linear can be fitted as ln R~ T -1/4 . Keywords: alloys, metallic glasses, resistivity, metals.
