Anomalous Hall effect and magnetic structure of the topological semimetal (Mn0.78Fe0.22)3Ge
Me3+8Ge, being a Weyl semimetal, shows a large anomalous Hall effect (AHE), which decreases slowly with an increase in 8 from 0.1 to 0.4. However, AHE in this compound remains significantly large in the whole range of 8 because of the robust nature of the ...
AMER PHYSICAL SOC2023Real space and reciprocal space investigations of the spin dynamics in skyrmion-hosting materials
Magnetic skyrmions are whirl-like spin configurations with particle-like properties protected by non-trivial topology. Due to their unique spin structures and dynamical properties, they have attracted tremendous interests over the past decade, from fundame ...
EPFL2022Investigating field-induced magnetic order in Han purple by neutron scattering up to 25.9 T
Frédéric Mila, Bruce Normand, Philippe Heller, Nicolas Laflorencie
BaCuSi2O6 is a quasi-two-dimensional (2D) quantum antiferromagnet containing three different types of stacked, square-lattice bilayer hosting spin-1/2 dimers. Although this compound has been studied extensively over the last two decades, the critical appli ...
AMER PHYSICAL SOC2022Small-angle neutron scattering study of mesoscale magnetic disordering and skyrmion phase suppression in the frustrated chiral magnet Co6.75Zn6.75Mn6.51
Henrik Moodysson Rønnow, Jonathan White
Co-Zn-Mn chiral cubic magnets display versatile magnetic skyrmion phases, including equilibrium phases stable far above and far below room temperature, and the facile creation of robust far-from-equilibrium skyrmion states. In this system, compositional di ...
INT UNION CRYSTALLOGRAPHY2022Static and dynamic properties of non-collinear quantum antiferromagnets explored by neutron scattering
This thesis is devoted to the investigation of static and dynamic properties of
two different sets of quantum magnets with neutron scattering techniques and
the help of linear spin wave theory.
Both systems are copper-based with spin-1/2, which makes them ...
EPFL2021Spin waves in the collinear antiferromagnetic phase of Mn5Si3
By combining two independent approaches, inelastic neutron-scattering measurements and density-functionaltheory calculations, we study the spin waves in the collinear antiferromagnetic phase (AFM2) of Mn5Si3. We obtain its magnetic ground-state properties ...
AMER PHYSICAL SOC2021Multiphase magnetism in Yb2Ti2O7
We use neutron scattering to show that ferromagnetism and antiferromagnetism coexist in the low T state of the pyrochlore quantum magnet Yb2Ti2O7. While magnetic Bragg peaks evidence long-range static ferromagnetic order, inelastic scattering shows that sh ...
NATL ACAD SCIENCES2020Phonon Lifetimes Throughout the Brillouin Zone at Elevated Temperatures from Experiment and ab initio
We obtain phonon lifetimes in aluminium by inelastic neutron scattering experiments, by ab initio molecular dynamics, and by perturbation theory. At elevated temperatures significant discrepancies are found between experiment and perturbation theory, which ...
2019Thermodynamic evidence of a second skyrmion lattice phase and tilted conical phase in Cu2OSeO3
Precision measurements of the magnetization and ac susceptibility of Cu2OSeO3 are reported for magnetic fields along different crystallographic directions, focusing on the border between the conical and the field-polarized state for a magnetic field along ...
2018Reentrant magnetism at the borderline between long-range antiferromagnetic order and spin-glass behavior in the B-site disordered perovskite system Ca2-x SrxFeRuO6
We report on the coexistence of magnetic order and disorder in the atomically disordered double perovskites Ca2FeRuO6 and CaSrFeRuO6. Powder x-ray and neutron diffraction were used to investigate the crystal structure and magnetic ordering of these oxides. ...
