Two-current model of the composition dependence of resistivity in amorphous (Fe100−xCox)89−yZr7B4Cuy alloys using a rigid-band assumption
2018
Composition dependence of resistivity is studied in amorphous (Fe100−xCox)89−yZr7B4Cuy (0 ≤ x ≤ 50, y = 0, 1) alloys. The two-current model proposed by Mott for crystalline materials is extended to a disordered amorphous system where s-d scattering is dominant in electron conduction. A rigid-band assumption is made due to the small atomic number difference between Fe and Co. Band structures with a constant density of states (DOS), parabolic distributed DOS, and Gaussian distributed DOS were
