Electronic structure and x-ray magnetic circular dichroism in uranium monochalcogenides
The electronic structure and x-ray magnetic circular dichroism (XMCD) spectra of US, USe, and UTe are investigated theoretically from first principles, using the fully relativistic Dirac LMTO band structure method. The electronic structure is obtained with the local spin-density approximation (LS...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The electronic structure and x-ray magnetic circular dichroism (XMCD) spectra of US, USe,
and UTe are investigated theoretically from first principles, using the fully relativistic Dirac
LMTO band structure method. The electronic structure is obtained with the local spin-density approximation
(LSDA), as well as with a generalization of the LSDA+U method which takes into account
that in the presence of spin–orbit coupling the occupation matrix of localized electrons becomes
non-diagonal in spin indexes. The origin of the XMCD spectra in the compounds is
examined. |
