Role of the d-f Coulomb interaction in intermediate valence and Kondo systems: a numerical renormalization group study
A. K. Zhuravlev, V. Yu. Irkhin, M. I. Katsnelson
Using numerical renormalization group method the temperature dependences of the magnetic susceptibility and specific heat are obtained in the single-impurity Anderson…
Spin-polarized scanning tunneling microscopy of half-metallic ferromagnets: Non-quasiparticle contributions
V. Yu. Irkhin, M. I. Katsnelson
The role of the many-body (spin-polaronic) effects in the scanning tunneling spectroscopy of half-metallic ferromagnets (HMF) is considered. It is shown that the non-quasiparticle…
Sum rules for X-ray magnetic circular dichroism spectra in strongly correlated ferromagnets
V. Yu. Irkhin, M. I. Katsnelson
It is proven that the sum rules for X-ray magnetic dichroism (XMCD) spectra that are used to separate spin and orbital contributions to the magnetic moment are formally correct for…
Spin and orbital ferromagnetism in strongly correlated itinerant electron systems
V. Yu. Irkhin, M. I. Katsnelson
Spectra of one-electron and collective excitations in narrow-band ferromagnets with unquenched orbital moments are calculated in various theoretical models. The interaction of spin…
