The Generalization of the Kinetic Equations and the Spectral Conductivity Function to Anisotropic Systems:Case T-Al72.5Mn21.5Fe6 Complex Metallic Alloy
Electrical conductivity, sigma, and thermoelectric power, S, of the monocrystalline T-Al72.5Mn21.5Fe6 complex metallic alloy have been investigated in the temperature range from 2 to 300 K. The crystallographic-direction-dependent measurements were performed along the [0 0 1], [0 1 0] and [1 0 0] di...

Electrical conductivity, sigma, and thermoelectric power, S, of the monocrystalline T-Al72.5Mn21.5Fe6 complex metallic alloy have been investigated in the temperature range from 2 to 300 K. The crystallographic-direction-dependent measurements were performed along the [0 0 1], [0 1 0] and [1 0 0] directions of the orthorhombic unit cell, where the stacking direction is along the [0 1 0] direction. The electrical conductivity exhibits a very small anisotropy, and in all directions shows the non-metallic behaviour with square root, root T, temperature behaviour and finite value in the T = 0 limit. Spectral conductivity function, sigma(s)(E), constructed out of measurements, reflects anisotropy of the experimental data and indicate non-analytic square root like singularity at Fermi level. Asymmetry of the spectral conductivity function has been extracted from the thermoelectric power data. |
