Magnetic ground state and perturbations of the distorted kagome Ising metal TmAgGe
C. B. Larsen, D. G. Mazzone, N. Gauthier +7
We present the magnetic orders and excitations of the distorted kagome intermetallic magnet TmAgGe. Using neutron single crystal diffraction we identify the propagation vectors $\b…
Dipolar-octupolar correlations and hierarchy of exchange interactions in CeHfO
Victor Porée, Anish Bhardwaj, Elsa Lhotel +9
High-resolution neutron spectroscopy on CeHfO reveals a correlated state characterized by distinct dipolar scattering signals -- quasi-elastic and inelastic contributio…
Crystal-field states and defect levels in candidate quantum spin ice CeHfO
Victor Porée, Elsa Lhotel, Sylvain Petit +8
We report the synthesis of powder and single-crystal samples of the cerium pyrohafnate and their characterization using neutron diffraction, thermogravimetry and X-ray absorption s…
Anisotropic quasiparticle coherence in nematic BaFeAs studied with strain-dependent ARPES
H. Pfau, S. D. Chen, M. Hashimoto +7
The hallmark of nematic order in iron-based superconductors is a resistivity anisotropy but it is unclear to which extent quasiparticle dispersions, lifetimes and coherence contrib…
Neutron scattering by magnetic octupoles of a quantum liquid
Nicolas Gauthier, Victor Porée, Sylvain Petit +4
Neutron scattering is a powerful tool to study magnetic structures and dynamics, benefiting from a precisely established theoretical framework. The neutron dipole moment interacts…
Quantum well states in fractured crystals of the heavy fermion material CeCoIn
Nicolas Gauthier, Jonathan A. Sobota, Makoto Hashimoto +6
Quantum well states appear in metallic thin films due to the confinement of the wave function by the film interfaces. Using angle-resolved photoemission spectroscopy, we unexpected…
A quantum liquid of magnetic octupoles on the pyrochlore lattice
Romain Sibille, Nicolas Gauthier, Elsa Lhotel +13
Spin liquids are highly correlated yet disordered states formed by the entanglement of magnetic dipoles. Theories typically define such states using gauge fields and deconfined…
Neutron scattering signatures of a quantum spin ice
Romain Sibille, Nicolas Gauthier, Han Yan +8
Quantum spin ice is an appealing proposal of a quantum spin liquid - systems where the magnetic moments of the constituent electron spins evade classical long-range order to form a…
Coexistence of magnetic fluctuations and long-range orders in the one-dimensional zigzag chains materials BaDyO and BaHoO
Bobby Prévost, Nicolas Gauthier, Vladimir Y. Pomjakushin +4
The compounds BaDyO and BaHoO are part of a family of frustrated systems exhibiting interesting properties, including spin liquid-type ground states, magnetic field…
Unconventional field induced phases in a quantum magnet formed by free radical tetramers
Andres Saul, Nicolas Gauthier, Reza Moosavi Askari +11
We report experimental and theoretical studies on the magnetic and thermodynamic properties of NIT-2Py, a free radical-based organic magnet. From magnetization and specific heat me…
Investigation of the commensurate magnetic structure in heavy fermion CePt2In7 using magnetic resonant X-ray diffraction
Nicolas Gauthier, Didier Wermeille, Nicola Casati +4
We investigated the magnetic structure of the heavy fermion compound CePtIn below K using magnetic resonant X-ray diffraction at ambient pressure. The magnet…
Experimental signatures of emergent quantum electrodynamics in PrHfO
Romain Sibille, Nicolas Gauthier, Han Yan +8
In a quantum spin liquid, the magnetic moments of the constituent electron spins evade classical long-range order to form an exotic state that is quantum entangled and coherent ove…
Candidate quantum spin ice in the pyrochlore PrHfO
Romain Sibille, Elsa Lhotel, Monica Ciomaga Hatnean +5
We report the low temperature magnetic properties of the pyrochlore PrHfO. Polycrystalline and single-crystal samples are investigated using time-of-flight neutron spec…
Magnetic structure of the antiferromagnetic half-Heusler compound NdBiPt
R. A. Mueller, A. Desilets-Benoit, N. Gauthier +9
We present results of single crystal neutron diffraction experiments on the rare-earth, half-Heusler antiferromagnet (AFM) NdBiPt. This compound exhibits an AFM phase transition at…
