Robust Kagome Electronic Structure in Topological Quantum Magnets XMn6Sn6 (X = Dy, Tb, Gd, Y)

X. Gu, C. Chen, W. S. Wei +24

Crystal geometry can greatly influence the emergent properties of quantum materials. As an example, the kagome lattice is an ideal platform to study the rich interplay between topo…

Correlated electron metal properties of the honeycomb ruthenate Na $_{2}$ RuO $_{3}$

L. S. I. Veiga, M. Etter, E. Cappelli +7

We report the synthesis and characterisation of polycrystalline Na $_{2}$ RuO $_{3}$ , a layered material in which the Ru $^{4 +}$ ( $4 d^{4}$ configuration) form a honeycomb lattice. The optima…

Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator

P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14

Here we investigate antiferromagnetic Eu $_{5}$ In $_{2}$ Sb $_{6}$ , a nonsymmorphic Zintl phase. Our electrical transport data show that Eu $_{5}$ In $_{2}$ Sb $_{6}$ is remarkably insulati…

Spontaneous cycloidal order mediating a spin-reorientation transition in a polar metal

C. D. Dashwood, L. S. I. Veiga, Q. Faure +9

We show how complex modulated order can spontaneously emerge when magnetic interactions compete in a metal with polar lattice distortions. Combining neutron and resonant x-ray scat…

Unveiling charge density wave quantum phase transitions by x-ray diffraction

F. B. Carneiro, L. S. I. Veiga, J. R. L. Mardegan +4

We investigate the thermal-driven charge density wave (CDW) transition of two cubic superconducting intermetallic systems Lu(Pt1-xPdx)2In and (Sr1-xCax)3Ir4Sn13 by means of x-ray d…

High-resolution resonant inelastic x-ray scattering study of the electron-phonon coupling in honeycomb $α$ -Li $_{2}$ IrO $_{3}$

J. G. Vale, C. D. Dashwood, E. Paris +11

The excitations in honeycomb $α$ -Li $_{2}$ IrO $_{3}$ have been investigated with high-resolution resonant inelastic x-ray scattering (RIXS) at the O K edge. The low-energy response is do…
