Coexisting polarization mechanisms in ferroelectric uniaxial tetragonal tungsten bronze Ca_0.3Ba_0.7Nb_2O_6

E. Buixaderas, Š. Svirskas, C. Kadlec +6

Using a broad band dielectric spectroscopy approach (1 to 10^14 Hz) we prove that the tungsten bronze Ca0.3Ba0.7Nb2O6 (CBN-30) displays a ferroelectric phase transition of mixed di…

Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite $B i M n_{7} O_{12}$

A. Maia, M. Kempa, V. Bovtun +6

We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of $B i M n_{7} O_{12}$ ceramics, shedding more light into the nature of two structural phase tran…

Microwave magnetic excitations in U-type hexaferrite Sr $_{4}$ CoZnFe $_{36}$ O $_{60}$ ceramics

M. Kempa, V. Bovtun, D. Repček +3

Microwave (MW) transmission, absorption, and reflection loss spectra of the ferrimagnetic U-type hexaferrite Sr $_{4}$ CoZnFe $_{36}$ O $_{60}$ ceramics were studied from 100 MHz to 35 GH…
