Correlation-Driven Orbital Order Realizes 2D Metallic Altermagnetism
Nirmalya Jana, Atasi Chakraborty, Anamitra Mukherjee +1
Two-dimensional metallic altermagnets are rare, and no correlated 2D material has been established to host large nonrelativistic spin splitting. Here we show that spontaneous orbit…
Interplay of phonons, intertwined density waves, and induced spin density wave in trilayer nickelates Pr4-xLaxNi3O10
Sonia Deswal, Dibyata Rout, Nirmalya Jana +3
Lattice degrees of freedom (DoF) play a central role in correlated electron systems, strongly influencing the dynamics of the underlying charge carriers and spin excitations. In ni…
Atomistic origin of low thermal conductivity in quaternary chalcogenides Cu(Cd, Zn)InTe
Nirmalya Jana, Amit Agarwal, Koushik Pal
Crystalline semiconductors with intrinsically low lattice thermal conductivity () are vital for device applications such as barrier coatings and thermoelectrics. Quate…
Layered Topological Antiferromagnetic Metal at Room Temperature -- YbMnGe
Nirmalya Jana, Atasi Chakraborty, Anamitra Mukherjee +1
Metallic antiferromagnets are essential for efficient spintronic applications due to their fast switching and high mobility, yet room-temperature metallic antiferromagnets are rare…
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…
Anisotropic magnetization dynamics in Fe5GeTe2 at room temperature
Alapan Bera, Nirmalya Jana, Amit Agarwal +1
The determination of Lande's g-factor and the damping constant is central to extracting crucial information about the spin-spin and spin-orbit interactions in magnetically ordered…
