Disentangling the ferroelectric phases of epitaxial hafnia
Johanna van Gent Gonzalez, Ewout van der Veer, Yulei Li +2
Since its discovery, ferroelectric hafnia has been extensively studied due to its CMOS-compatibility and ability to remain polarized at sub-10 nm thicknesses. The ferroelectric beh…

Interplay of Charge and Magnetic Orders in SmNiC Mediated by Electron-Phonon Interaction
A. von Ungern-Sternberg Schwark, A. -A. Haghighirad, R. Heid +11
We investigate the interplay between charge density wave (CDW) instabilities and ferromagnetism in SmNiC using diffuse and inelastic x-ray scattering together with Raman spectr…

Charge density waves and soft phonon evolution in the superconductor BaNi(AsP)
Tom Lacmann, Sofia-Michaela Souliou, Fabian Henssler +8
The superconductor BaNiAs exhibits a soft-phonon-driven, incommensurate charge density wave (I-CDW) which is accompanied by a small orthorhombic structural phase transition…
