Magnetic circular dichroism of THz modes and selection rules of Raman-active optical phonons in the polar altermagnet candidate \ce{Mn2Mo3O8}
F. Schilberth, K. Vasin, M. Knauft +14
We investigated the magnetic and vibrational excitations in the collinear altermagnet candidate \ce{Mn2Mo3O8} by temperature dependent Raman scattering and magneto-optical THz time…
Universality of magnetic susceptibility in the conical state of kagome ferromagnet FeSn
Lilian Prodan, Donald M. Evans, Lukas Puntigam +2
We report universal behavior of the differential magnetic susceptibility (DMS) in the conical phase that mediates the spin-reorientation (SR) transition of the kagome ferromagnet F…
From Wavefunction Collapse to Superconductivity: Evolution of the Electronic State in Compressed GaNb4Se8
Yuejian Wang, Zhongyan Wu, K C Bhupendra +5
Understanding how electronic transport evolves from localized to itinerant regimes in correlated cluster solids remains an important challenge in condensed-matter physics. Here we…
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…
