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…
Field-Angle Dependence of Phonon Thermal Hall Effect in Na2X2TeO6 (X = Co, Zn)
Jian Yan, Hikaru Takeda, Haruka Iwahata +5
The mechanism behind thermal Hall effects by phonons, which are observed in various materials, is not clarified despite the dominant contribution as heat carriers. Theoretically, m…
Coexistence of anomalous spin dynamics and weak magnetic order in a chiral trillium lattice K2FeSn(PO4)3
J. Khatua, S. Krishnamoorthi, Changhyun Koo +13
Trillium lattices, where magnetic ions form a three-dimensional chiral network of corner-sharing equilateral triangular motifs, offer a prominent platform to explore exotic quantum…
Direct Visualization of a Disorder Driven Electronic Smectic Phase in Nonsymmorphic Square-Net Semimetal GdSbTe
Balaji Venkatesan, Syu-You Guan, Jen-Te Chang +14
Electronic liquid crystal (ELC) phases are spontaneous symmetry breaking states believed to arise from strong electron correlation in quantum materials such as cuprates and iron pn…
Spin waves in NaCoTeO studied by high-frequency/high-field ESR: Successes and failures of the triple- model
Luca Bischof, Jan Arneth, Raju Kalaivanan +3
The Kitaev candidate material NaCoTeO is proposed to be proximate to a quantum spin liquid state but a suitable spin model and the nature of its ground states are still…
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…
