Raman scattering signatures of the strong spin-phonon coupling in the bulk magnetic van der Waals material CrSBr
Amit Pawbake, Thomas Pelini, Nathan P. Wilson +4
Magnetic excitations in layered magnetic materials that can be thinned down the two-dimensional (2D) monolayer limit are of high interest from a fundamental point of view and for a…
Strong electron-phonon coupling and enhanced phonon Grüneisen parameters in valence-fluctuating metal EuPdSi
Mai Ye, Mark Joachim Graf von Westarp, Sofia-Michaela Souliou +7
We study the valence crossover and strong electron-phonon coupling of EuPdSi by polarization-resolved Raman spectroscopy. The fully-symmetric phonon mode shows strongly asy…
An Electronic Nematic Liquid in BaNiAs
Yi Yao, Roland Willa, Tom Lacmann +10
Understanding the organizing principles of interacting electrons and the emergence of novel electronic phases is a central endeavor of condensed matter physics. Electronic nematici…
Charge-density-wave transitions, phase diagram, soft phonon and possible electronic nematicity: a thermodynamic investigation of BaNi2(As,P)2
Christoph Meingast, Anmol Shukla, Liran Wang +9
A detailed investigation of BaNi2(As,P)2 single crystals using high-resolution thermal-expansion, heat-capacity,Young-modulus and resistivity measurements is presented. The experim…
Soft-phonon and charge-density-wave formation in nematic BaNiAs
S. M. Souliou, T. Lacmann, R. Heid +7
We use diffuse and inelastic x-ray scattering to study the formation of an incommensurate charge-density-wave (I-CDW) in BaNiAs, a candidate system for charge-driven electr…
A combined inelastic neutron scattering and \textit{ab initio} lattice dynamics study of FeSi
Nazir Khan, Sven Krannich, Dominic Boll +5
The phonon renormalization across the semiconductor-to-metal crossover in FeSi is investigated by inelastic neutron scattering combined with \textit{ab-initio} lattice dynamical ca…
