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…

Phonon studies of the phase transition sequence in antiferroelectric single crystal of Pb(Hf0.83Sn0.17)O3
Anirudh K. R., Cosme Milesi-Brault, Christelle Kadlec +5
The sequence of phase transitions in PbHf0.83Sn0.17O3 has been studied by THz, far infrared and Raman spectroscopies, revealing the complementary behaviour of both, polar and non-p…

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…
