Transport properties of ferromagnetic metallic glasses: Resistivity and magnetoresistance effect

Electrical resistivity and magnetoresistance measurements from 4K to 300K on Metglas 2605 and Metglas 2605 A are reported. For both materials a resistivity minimum appears at low temperatures. Below the minimum an approximately logarithmic increase of resistivity was found. Magnetoresistance measurements were used to get additional information about the electronic conduction, magnetic texture and the nature of the magnetization process in these alloys. The anisotropic magnetoresistivity was found to increase with decreasing temperature.
