Magnetic and electron transport study of amorphous metallic alloys FeNiBSi

Magnetic and electron transport properties of the amorphous metallic alloys FeNiBSi are investigated up to the crystallization temperature. Magnetic measurements reveal a speromagnetic structure of amorphous metallic alloys FeNiBSi and the increase of the spin wave stiffness constant with iron content. Influence of the ferro- to paramagnetic transition on electrical resistivity and thermoelectric power is observed. Magnetic contributions to electrical resistivity and thermoelectric power are separated and their temperature dependences are determined and discussed.
