Electron spectrum, thermodynamics, and transport in antiferromagnetic metals at low temperatures
Electron spectrum, thermodynamics, and transport in antiferromagnetic metals at low temperatures
Electron spectrum of two-dimensional (2D) and 3D antiferromagnetic metals is calculated with an account of spin-fluctuation corrections within perturbation theory in the $s\ensuremath{-}f$ exchange model. Effects of the interaction of conduction electrons with spin waves in thermodynamic and transport properties are investigated. At lowest temperatures $T<{T}^{*}\ensuremath{\sim}(\ensuremath{\Delta}{/E}_{F}{)T}_{N}$ (\ensuremath{\Delta} is the AFM …
