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…
