perovskite-structured BiFeO3–Bi(Zn1/2Ti1/2)O3–PbTiO3 (BF–BZT–PT) ternary solid solutions were prepared with traditional solid-state reaction method and demonstrated to exhibit a coexistent phase boundary (CPB) with Curie temperature of TC~700°C in the form of ceramics with microstructure ...
(1-x)(Bi0.8Gd0.2)FeO3-xPbTiO3(BGF-PT) solid solutions ceramics of x=0.55,0.50,0.4975, 0.49 and 0.45 were prepared by the mixed oxide method. Gd3+of 20 at% was introduced into the Bi3+site to improve the dielectric and piezoelectric properties of BFPT without causing the significant re...

Piezoelectric and electrostrictive properties of ceramic Pb(Zn1/3Nb2/3)O3–PbZrO3–PbTiO3 pseudoternary system have been studied. In these ceramics prepared by the conventional ceramic processing, both perovskite (ferroelectric) and pyro... T Kato,M Sato,A Imai - 《Japanese Journal of Applied...
56, no. 8, aUgUsT 2009Abstract—Piezoresponse force microscopy (PFM) was used to investigate the domain structure of multiferroic BiFeO3-PbTiO3 single crystals with morphotropic phase boundary (MPB) compositions. The PFM data demonstrate the piezo-electricity and the PFM domain responses under the ...
