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…
Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite
A. Maia, M. Kempa, V. Bovtun +6
We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of ceramics, shedding more light into the nature of two structural phase tran…
Microwave magnetic excitations in U-type hexaferrite SrCoZnFeO ceramics
M. Kempa, V. Bovtun, D. Repček +3
Microwave (MW) transmission, absorption, and reflection loss spectra of the ferrimagnetic U-type hexaferrite SrCoZnFeO ceramics were studied from 100 MHz to 35 GH…
Multiferroic quantum criticality in (Eu,Ba,Sr)TiO solid solution
Dalibor Repček, Petr Proschek, Maxim Savinov +6
Based on the earlier published theory (\textit{Nature Mat}. \textbf{18}, 223--228 (2019)), a comprehensive experimental investigation of multiferroic quantum critical behavior of (…
Strong impact of low-level substitution of Mn by Fe on the magnetoelectric coupling in
A. Maia, R. Vilarinho, P. Proschek +6
The correlation between static magnetoelectric coupling and magnetic structure was investigated in with magnetic field up to 8 T and down to 2 K. Single…
