Chiral Weyl--Kondo semimetal and circular photogalvanic effect in a prototype Kondo lattice system

Yuan Fang, Kuan-Sen Lin, Mounica Mahankali +5

Chiral Weyl--Kondo semimetals (cWKSM) provide a setting in which chiral Weyl quasiparticles emerge in the immediate vicinity of the Fermi energy from a Kondo-driven reconstruction…

Chiral Weyl-Kondo semimetallic state through enhanced correlation in CeGaGe

Arushi, Kevin Allen, Yuan Fang +11

Strongly correlated chiral materials have been proposed to host a chiral Weyl-Kondo semimetal (cWKSM) state, in which Kondo hybridization pins chirality-induced Kramers-Weyl point…

Competing collinear and non-collinear spin textures imaged by spatially-resolved REXS in Eu(Al0.4Ga0.6)4

Fellipe B. Carneiro, Zéetény Bacsó, Kevin Allen +6

Here, we use resonant elastic x-ray scattering (REXS) to investigate the inhomogeneity of the zero-field magnetic spin texture of Eu(Al $_{0.4}$ Ga $_{0.6}$ ) $_{4}$ . By using spatially-r…

Electron-phonon coupling in EuAl4 under hydrostatic pressure

A. S. Sukhanov, S. Gebel, A. N. Korshunov +7

In the intermetallid rare-earth tetragonal EuAl4 system, competing itinerant exchange mechanisms lead to a complex magnetic phase diagram, featuring a centrosymmetric skyrmion latt…

Correlation between Complex Spin Textures and the Magnetocaloric and Hall Effects in Eu(Ga $_{1 - x}$ Al $_{x}$ ) $_{4}$ ( $x$ = 0.9, 1)

Kelly J. Neubauer, Kevin Allen, Jaime M. Moya +7

Determining the electronic phase diagram of a quantum material as a function of temperature (T) and applied magnetic field (H) forms the basis for understanding the microscopic ori…

Incommensurate magnetic orders and topological Hall effect in the square-net centrosymmetric EuGa $_{2}$ Al $_{2}$ system

Jaime M. Moya, Shiming Lei, Eleanor M. Clements +16

Neutron diffraction on the centrosymmetric square-net magnet EuGa $_{2}$ Al $_{2}$ reveals multiple incommensurate magnetic states (AFM1,2,3) in zero field. In applied field, a new magnet…
