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…
