Contrasting magnetic behavior in MnSc_2X_4 (X = S, Se) spinel compounds investigated by magnetoelastic studies
J. Grumbach, J. Sourd, M. Deeb +12
The spinel compounds MnSc_2X_4 are highly frustrated and candidate materials for vortex-like 3q magnetic states, such as skyrmions, with propagation vectors in the [111] plane. Bec…
Magnetism and electronic dynamics in spinels studied by transferred hyperfine fields at and muon spin rotation and relaxation
Elaheh Sadrollahi, Cynthia P. C. Medrano, Magno A. V. Heringer +4
We investigated magnetization, muon spin rotation (SR), and Mössbauer spectroscopy on Sn substituted (x=0.03 and 0.08) spinel compounds. The mag…
Spatially resolving superconductivity in type-II superconductors
Donald M. Evans, Michele Conroy, Lukas Puntigam +6
Superconductivity is identified by the emergence of a macroscopic zero-resistance state, typically inferred from a vanishing four-probe voltage at finite current. That inference as…
Optical phonons as a testing ground for spin group symmetries
F. Schilberth, M. Kondákor, D. Ukolov +12
Lattice vibrations are highly sensitive to crystal symmetries and their changes across phase transitions. The latter can modify irreducible (co)representations and corresponding in…
All-optical stochastic switching of magnetization textures in FeSn
Jonathan T. Weber, András Kovács, Michalis Charilaou +9
The all-optical control of magnetization at room temperature broadens the scope of applications of spin degrees-of-freedom in data storage, spintronics, and quantum computing. Topo…
Easy-cone state mediating the spin reorientation in topological kagome magnet FeSn
L. Prodan, D. M. Evans, A. S. Sukhanov +7
We investigated temperature-driven spin reorientation (SR) in the itinerant kagome magnet FeSn using high-resolution synchrotron x-ray diffraction, neutron diffraction, mag…
