The Generalization of the Kinetic Equations and the Spectral Conductivity Function to Anisotropic Systems: Case T-Al72.5Mn21.5Fe6 Complex Metallic Alloy
We have investigated electrical conductivity, σ, and thermoelectric power, S, of the monocrystalline T-Al72.5Mn21.5Fe6 complex metallic alloy in the temperature range from 2 to 300 K. The crystallographic-direction-dependent measurements were performed along the [001], [010] and [100] directions of the orthorhombic unit cell, where the stacking direction is along the [010] direction. The electrical conductivity exhibits a very small anisotropy, and in all directions shows the non-metallic behaviour with square root, , temperature behaviour and finite value in the T=0 limit. Spectral conductivity function, 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.
