Crystal field tuned spin-flip luminescence in NiPS3
Léonard Schue, Nashra Pistawala, Hebatalla Elnaggar +8
Layered magnetic materials potentially hold the key to future applications based on optical control and manipulation of magnetism. NiPS3, a prototype member of this family, is anti…
Spin-orbital excitations encoding the magnetic phase transition in the van der Waals antiferromagnet FePS
Yuan Wei, Yi Tseng, Hebatalla Elnaggar +13
In the rich phases of van der Waals (vdW) materials featuring intertwined electronic order and collective phenomena, characterizing elementary dynamics that entail the low-energy H…
General expressions for Stevens and Racah operator equivalents
Octave Duros, Amélie Juhin, Hebatalla Elnaggar +2
Several definitions of the crystal field have been used over time and their variety has lead to many misunderstandings, in both theoretical and experimental literature. Two categor…
Nature of excitons and their ligand-mediated delocalization in nickel dihalide charge-transfer insulators
Connor A. Occhialini, Yi Tseng, Hebatalla Elnaggar +7
The fundamental optical excitations of correlated transition-metal compounds are typically identified with multielectronic transitions localized at the transition-metal site, such…
Novel magnetic excitations beyond the single- and double-magnons
Hebatalla Elnaggar, Abhishek Nag, Maurits W. Haverkort +2
Conventional wisdom suggests that one photon that carries one unit of angular momentum can change the spin angular momentum of a magnetic system with one unit (delta Ms = +-1) at m…
Site selective spin and orbital excitations in Fe3O4
H. Elnaggar, R. Wang, S. Lafuerza +10
is a mixed-valence strongly correlated transition metal oxide which displays the intriguing metal to insulator Verwey transition. Here we investigate the electronic and m…
Investigation into the role of the orbital moment in a series of isostructural weak ferromagnets
D. Pincini, F. Fabrizi, G. Beutier +10
The orbital contribution to the magnetic moment of the transition metal ion in the isostructural weak ferromagnets ACO (A=Mn,Co,Ni) and FeBO was investigated by a combinati…
Experimental search for the violation of Pauli Exclusion Principle
H. Shi, E. Milotti, S. Bartalucci +25
The VIolation of Pauli exclusion principle -2 experiment, or VIP-2 experiment, at the Laboratori Nazionali del Gran Sasso searches for x-rays from copper atomic transition that are…
