Spin and orbital magnetic moments of UTe2 induced by the external magnetic field

Popis výsledku v původním jazyce

Correlated band theory implemented as a combination of the relativistic density functional theory withexact diagonalization [DFT+U(ED)] of the Anderson impurity term with Coulomb repulsion U in the5f shell is applied to the magnetic field polarized state of UTe2. We demonstrate that the DFT+U(ED)approach provides a good agreement with very recent x-ray absorbtion near edge structure (XANES)and x-ray magnetic circular dichroism (XMCD) experiments. The branching ratio for the M4,5 edgetransitions of uranium, and the valence spin-orbit interaction per hole were evaluated in a perfectagreement with the XANES. The orbital-to-spin moment ratio is calculated with DFT+U(ED) within therange of values extracted from XMCD data. The uranium atom 5f-shell ground state with 33 % of f2and 58 % of f3 configurations is determined. Both XMCD and DFT+U(ED) point out the intermediatevalence of uranium as well as itinerant-localized dichotomy in UTe2.
