Relaxor ferroelectrics with lanthanum perovskites
ISAF '92: Proceedings of the Eighth IEEE International Symposium on Applications of Ferroelectrics, 2003Lanthanum perovskite compounds La(B/sub 1/2//sup I/B/sub 1/2//sup II/)O/sub 3/ (B/sup I/=Ni,Co,Mg; B/sup II/=Ti) are studied as candidates for stabilizers to form perovskite-type Pb(Zn/sub 1/3/Nb/sub 2/3/)O/sub 3/ (PZN)-based ceramics. A conventional sintering technique is used to prepare ceramic samples with PZN-based solid solution. The ratios of the

A new relaxor ferroelectric, Ba2LaTi2Nb3O15
Journal of Materials Chemistry, 2002Ceramic samples of the tetragonal tungsten bronze Ba2LaTi2Nb3O15, containing B-site disorder of Ti,Nb, have a maximum permittivity of 250–300 at Tc ≈ 200 K and frequency-dependent permittivity below Tc, characteristic of relaxor behaviour.
