Paramagnon softening upon doping in oxychloride cuprate superconductors
Chafic Fawaz, Léo Gaspard, Laura Chaix +15
Understanding how magnetic excitations and exchange interactions evolve with doping is crucial for deciphering the physics that shapes the phase diagram of high-temperature cuprate…
Direct measurement of the longitudinal exciton dispersion in hBN by resonant inelastic x-ray scattering
Alessandro Nicolaou, Kari Ruotsalainen, Laura Susana +7
We report resonant inelastic X-ray scattering (RIXS) measurements on the prototypical hexagonal boron nitride hBN layered compound. The RIXS results at the B and N K edges have bee…
Resonant X-ray spectroscopies on Chromium orbitals in CrSBr
Victor Porée, Alberto Zobelli, Amit Pawbake +4
We investigate the Cr electronic structure and excitations in CrSBr, a layered magnetic semiconductor, using a combination of resonant x-ray spectroscopic techniques. X-ray absorpt…
YBaSrCuFeO layered perovskites: exploring the magnetic order beyond the paramagnetic-collinear-spiral triple point
Victor Porée, Dariusz J. Gawryluk, Tian Shang +5
Layered perovskites of general formula AA'CuFeO are one of the few examples of cycloidal spiral magnets where the ordering temperatures can be tuned far beyond roo…
Thermodynamics of the dipole-octupole pyrochlore magnet CeHfO in applied magnetic fields
Anish Bhardwaj, Victor Porée, Han Yan +7
The recently discovered dipole-octupole pyrochlore magnet CeHfO is a promising three-dimensional quantum spin liquid candidate which shows no signs of ordering at low t…
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…
Fractional matter coupled to the emergent gauge field in a quantum spin ice
Victor Porée, Han Yan, Félix Desrochers +7
Electronic spins can form long-range entangled phases of condensed matter named quantum spin liquids. Their existence is conceptualized in models of two- or three-dimensional frust…
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…
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…
