Hund's coupling driven nature of magnetism in negative charge transfer material,
Jyotsana Sharma, Shivani Bhardwaj, Sudhir K Pandey
In this work, we investigate the microscopic origin of magnetism in by incorporating electronic correlations within the dynamical mean-field theory (DMFT) framew…
Valence band-satellite, temperature dependent magnetic and spectral study of α-Fe
Trishu Verma, Shivani Bhardwaj, Sudhir K Pandey
We investigate the influence of correlations and plasmonic excitation on valence band-satellite of -Fe, along with magnetic and spectral properties as function of temperature. C…
Spin-dependent orbital selectivity and partial Kondo-screening in magnetically ordered Hund's metal
Shivani Bhardwaj, Sudhir K. Pandey
Hund's metallicity in 3 transition metal oxides constitutes a rare class of compounds, since they have been long understood considering the dominance of Hubbard . $\mathrm{Li…
Signatures of Hund metal physics in single-layered 3d transition metal oxide,
Shivani Bhardwaj, Sudhir K Pandey
With density functional theory plus dynamical mean-field theory, we study the influence of Hund's coupling on the nature of electronic correlations in . Our res…
Observation of correlation induced metal to half-metal phase transition and large orbital moment in
Shivani Bhardwaj, Sudhir K. Pandey
We present a detailed mean-field study to address the fundamental discrepancy in the ground state magnetization of (SCO). In contrast to the ferromagnetic…
