Electron spectrum, thermodynamics and transport in antiferromagnetic metals at low temperatures
V. Yu. Irkhin, M. I. Katsnelson
Electron spectrum of 2D and 3D antiferromagnetic metals is calculated with account of spin-fluctuation corrections within perturbation theory in the s-f exchange model. Effects of…
The Kondo effect in periodic narrow-band systems
V. Yu. Irkhin, A. V. Zarubin
The Kondo divergences owing to interaction of current carriers with local moments in highly correlated electron systems are considered within the Hubbard and s-d exchange models wi…
Spin-wave contributions to nuclear magnetic relaxation in magnetic metals
V. Yu. Irkhin, M. I. Katsnelson
The longitudinal and transverse nuclear magnetic relaxation rates and are calculated for three- and two-dimensional (3D and 2D) metallic ferro- and antiferrom…
Non-Fermi-liquid behavior in the Kondo lattices induced by peculiarities of magnetic ordering and spin dynamics
V. Yu. Irkhin, M. I. Katsnelson
A scaling consideration of the Kondo lattices is performed with account of singularities in the spin excitation spectral function. It is shown that a non-Fermi-liquid (NFL) behavio…
