Dielectric signatures of crystal-field and low-temperature correlated dynamics in NdMgAl11O19
Sonu Kumar, Gaël Bastien, Maxim Savinov +3
We report dielectric spectroscopy of single-crystalline \ce{NdMgAl11O19}, a magnetoplumbite hexaaluminate in which localized \ce{Nd^{3+}} moments coexist with a polarizable \ce{AlO…
Field-induced spin-flip and spin-flop transitions in NdFeO3
Mariana M. Gomes, Rui Vilarinho, E. Miranda +14
Magnetic control of correlated spin systems is central to the development of next-generation spin-based technologies. Rare-earth orthoferrites provide an interesting platform in wh…
Crystal-Field--Driven Magnetoelectric Coupling in the Non-Kramers Hexaaluminate PrMgAl11O19
Sonu Kumar, Gaël Bastien, Ross H. Colman +7
We report broadband dielectric spectra of the non-Kramers hexaaluminate PrMgAl\textsubscript{11}O\textsubscript{19}, revealing a pronounced interplay between permittivity and magne…
Phonon properties and unconventional heat transfer in quasi-2D crystal
Jan Zich, Antonín Sojka, Petr Levinský +10
Bi2O2Se belongs to a group of quasi-2D semiconductors that can replace silicon in future high-speed/low-power electronics. However, the correlation between crystal/band structure a…
A frustrated antipolar phase analogous to classical spin liquids
G. Bastien, D. Repček, A. Eliáš +17
The study of magnetic frustration in classical spin systems was motivated by the prediction and discovery of classical spin liquid states. These uncommon magnetic phases are charac…
