The temperature dependences of electrical resistance of Fe–B–P–Nb–Cr-system amorphous alloys are studied in the temperature range of 77–846 K. The values of their specific electrical resistance are somewhat higher than such values for the most of soft magnetic iron-based materials, but they are in accordance with general regularities of the electrical-resistance changes for amorphous alloys. The high values of specific electrical resistance and the small values of temperature coefficient of electrical resistance simultaneously with high magnetic characteristics determine the possibility of efficient use of such materials as magnetic conductors for various applications.
Key words: amorphous iron-based alloys, Nb and Cr impurities, electrical resistance, temperature coefficient of electrical resistance.
