Spin-reorientation as a switch for electronic topology in van der Waals ferromagnets
Satyabrata Bera, Sudipta Chatterjee, Suman Kalyan Pradhan +5
The interplay between spin reorientation and topological electronic structure in two-dimensional (2D) van der Waals (vdW) ferromagnets is central to understanding how magnetic anis…
Emergence of a hidden-order phase well below the charge density wave transition in a topological Weyl semimetal (TaSe)I
Sk Kalimuddin, Sudipta Chatterjee, Arnab Bera +7
The emergence of a charge density wave (CDW) in a Weyl semimetal -- a correlated topological phase, is exceptionally rare in condensed matter systems. In this context, the quasi-on…
The interplay of magnetic order with the electronic scattering and crystal-field effects in a metallic ferromagnet
Payel Shee, Tanaya Halder, Chia-Jung Yang +9
The interplay between magnetic order, charge dynamics, and crystal field excitations underpins the emergent ground states of rare-earth intermetallics. Using time-domain terahertz…
Emergent Quasiparticles \& Field-Tuned RIXS Spectra in a Trimerized Spin-1/2 Chain
Subhajyoti Pal, Pradeep Thakur, Ashis Kumar Nandy +1
We investigate spin-flip excitations in the spin-1/2 trimer chain , featuring an antiferromagnetic exchange motif -- with . Using d…
Terahertz crystal electric field transitions in a Kondo-lattice antiferromagnet
Payel Shee, Chia-Jung Yang, Shishir Kumar Pandey +5
Hybridization between the localized f-electrons and the delocalized conduction electrons together with the crystal electric field (CEF) play a determinant role in governing the man…
Pressure-Driven Transitions in La2CoTiO6: Antiferromagnetic Insulator to Nonmagnetic Metal via Antiferromagnetic Metal in a Double Perovskite Oxide
Sromona Nandi, Subhadip Pradhan, Ashis K. Nandy +1
In double perovskite oxides (ABBO), magnetism often arises from diluted magnetic lattices, created by combining a perovskite structure with localized 3 magnetic…
