Revealing magnetism in the distorted kagome TiBi ( = Nd, Sm, Gd) via ARPES and XMCD
C. Lim, F. Ballester, A. Kar +19
Kagome materials are known for hosting emergent quantum phenomena driven by the interaction between different lattice, charge and spin orders. Here, we present a detailed angle res…
Flat band driven itinerant magnetism in the Co-pnictides CaCoAs and LaCoP
D. Subires, M. GarcÃa-DÃez, A. Kar +12
Flat bands can induce strong electron correlation effects that help stabilize both magnetic and superconducting states. Here, we carry out angle-resolved photoemission spectroscopy…
First-order phase transition driven by competing charge-order fluctuations in 1T'-TaTe
S. K. Mahatha, A. Kar, J. Corral-Sertal +20
First-order phase transitions, characterized by a discontinuous change in the order parameter, are intriguing phenomena in condensed matter physics. However, the underlying, materi…
Magnetoelastic coupling in intercalated transition metal dichalcogenides
A. Kar, R. Basak, Xue Li +27
The large van der Waals gap in transition metal dichalcogenides (TMDs) offers an avenue to host external metal atoms that modify the ground state of these 2D materials. Here, we ex…
Cascade of pressure induced competing CDWs in the kagome metal FeGe
A. Korshunov, A. Kar, C. -Y. Lim +14
Electronic ordering is prevalent in correlated systems, which commonly exhibit competing interactions. Here, we use x-ray diffraction to demonstrate a cascade of pressure induced o…
