Spin-dependent orbital selectivity and partial Kondo-screening in magnetically ordered Hund's metal

Shivani Bhardwaj, Sudhir K. Pandey

Hund's metallicity in 3 $d$ transition metal oxides constitutes a rare class of compounds, since they have been long understood considering the dominance of Hubbard $U$ . $\mathrm{Li…
