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(AlGa). By using spatially-r…
Modification of Charge and Spin Textures by Light Chemical Substitution in Eu(AlGa) ()
Zétény Bacsó, Fellipe Carneiro, Kevin Allen +6
We present the results of a resonant X-ray diffraction experiment, resolving both charge and spin textures in the intermetallic topological magnet Eu(AlGa), =…
Correlation between Complex Spin Textures and the Magnetocaloric and Hall Effects in Eu(GaAl) ( = 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…
Spontaneous spin chirality reversal and competing phases in the topological magnet EuAl
A. M. Vibhakar, D. D. Khalyavin, F. Orlandi +4
We demonstrate the spontaneous reversal of spin chirality in a single crystal sample of the intermetallic magnet EuAl. We solve the nanoscopic nature of each of the four magnet…
Phonon softening and atomic modulations in EuAl
A. N. Korshunov, A. S. Sukhanov, S. Gebel +6
EuAl is a rare earth intermetallic in which competing itinerant and/or indirect exchange mechanisms give rise to a complex magnetic phase diagram, including a centrosymmetric s…
Competing charge and magnetic order in the candidate centrosymmetric skyrmion host EuGaAl
A. M. Vibhakar, D. D. Khalyavin, J. M. Moya +5
Eu(GaAl) are centrosymmetric systems that have recently been identified as candidates to stabilise topologically non-trivial magnetic phases, such as skyrmion latti…
Symmetry-mode analysis for local structure investigations using pair distribution function data
Parker K. Hamilton, Jaime M. Moya, Alannah M. Hallas +3
Symmetry-adapted distortion modes provide a natural way to describe distorted structures derived from higher-symmetry parent phases. Structural refinements using symmetry-mode ampl…
Real-space and reciprocal-space topology in the Eu(GaAl) square net system
Jaime M. Moya, Jianwei Huang, Shiming Lei +5
Magnetotransport measurements on the centrosymetric square-net Eu(GaAl) compounds reveal evidence for both reciprocal- and real-space topology. For compositions $0.…
Quantum Simulation of an Extended Dicke Model with a Magnetic Solid
Nicolas Marquez Peraca, Xinwei Li, Jaime M. Moya +13
The Dicke model describes the cooperative interaction of an ensemble of two-level atoms with a single-mode photonic field and exhibits a quantum phase transition as a function of l…
Weyl nodal ring states and Landau quantization with very large magnetoresistance in square-net magnet EuGa
Shiming Lei, Kevin Allen, Jianwei Huang +17
Magnetic topological semimetals (TSMs) allow for an effective control of the topological electronic states by tuning the spin configuration, and therefore are promising materials f…
Incommensurate magnetic orders and topological Hall effect in the square-net centrosymmetric EuGaAl system
Jaime M. Moya, Shiming Lei, Eleanor M. Clements +16
Neutron diffraction on the centrosymmetric square-net magnet EuGaAl reveals multiple incommensurate magnetic states (AFM1,2,3) in zero field. In applied field, a new magnet…
Charge neutral fermions and magnetic field driven instability in insulating YbIrSi
Y. Sato, S. Suetsugu, T. Tominaga +12
Materials where localized magnetic moments are coupled to itinerant electrons, the so-called Kondo lattice materials, provide a very rich backdrop for strong electron correlations.…
Field-induced quantum critical point in the new itinerant antiferromagnet TiCu
Jaime M. Moya, Alannah M. Hallas, Vaideesh Loganathan +13
New phases of matter emerge at the edge of magnetic instabilities. In local moment systems, such as heavy fermions, the magnetism can be destabilized by pressure, chemical doping,…
