Tuning magnetic, lattice, and transport properties in CoNb3S6 via Fe doping
Deepu Kumar, Joydev Khatua, Mukesh Suthar +9
We present a comprehensive investigation of the effects of Fe doping on the lattice dynamics, magnetic ordering, and magneto-transport properties of the intercalated van der Waals…
Manipulation of anisotropic Zhang-Rice exciton in van der Waals antiferromagnets NiPS3-xSex by anion substitution
Deepu Kumar, Joydev Khatua, Nguyen The Hoang +6
Spin-entangled excitons have emerged as intriguing quasi-particle excitations in van der Waals magnets. Among them, the recently observed Zhang-Rice (ZR) exciton in NiPS3 has garne…
Raman signature of multiple phase transitions and quasi-particle excitations in putative Kitaev spin liquid candidate Na2Co2TeO6
Atul G. Chakkar, Chaitanya B. Auti, Deepu Kumar +3
Two-dimensional cobalt-based honeycomb oxide Na2Co2TeO6 is an important candidate for the realization of Kitaev physics and may provide future platform for the quantum computation…
Interplay between magnetic and lattice excitations and emergent multiple phase transitions in MnPSe3-xSx
Deepu Kumar, Nguyen The Hoang, Yumin Sim +6
The intricate interplay between spin and lattice degrees of freedom in two-dimensional magnetic materials plays a pivotal role in modifying their magnetic characteristics, engender…
