“…The lattice parameter and dielectric permittivity of PFW-PT solid solutions have been briefly reported. [15][16][17] However, a systematic dielectric study on these solid solutions has not yet been done. The present work reports the dielectric properties of PF-W-PT solid solutions together with their variation with postsintering annealing treatments.…”

The dielectric properties of (1؊x)Pb(Fe 2/3 W 1/3 )O 3 ⅐xPbTiO 3 solid solutions were investigated from 10 2 to 10 6 Hz in the temperature range 150 -600 K. The phase transition of Pb(Fe 2/3 W 1/3 )O 3 (PFW) was shifted by PbTiO 3 (PT) additions to higher temperatures at a rate of 6.3 K/mol% of PT. The temperature dependence of dielectric permittivity showed a sharper transition as the PT content increased. Dielectric measurements in a wide temperature range showed the presence of a second set of dielectric peaks at higher temperatures (350 -600 K), besides the ferroelectric-paraelectric phase transition. This second set of peaks vanished when the samples were annealed in nitrogen. The activation energy values for the second relaxation varied between 0.50 and 0.63 eV, in agreement with the conduction activation energy determined for each sample. This relaxation is apparently related to electron holes.

“…A long-range ferroelectric order may be introduced by alloying PFWO with rare earth elements and transition metals. Results from studies using various solid solutions have been reported, for instance, by A-site substitution with Ba 2+ , Sr 2+ , Ca 2+ and La 3+ [17][18][19][20][21] and B-site substitution with Ni 2+ , Mg 2+ , Co 2+ , Cr 3+ , Mn 3+ , Ti 4+ , Zr 4+ [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37], or addition of PbTiO 3 [38][39][40]. These studies show that cation doping is an effective method to tune the magnetic and dielectric properties of PFWO.…”

Ceramic samples of the multiferroic perovskite Pb(Fe1−xScx) 2/3 W 1/3 O3 with 0 ≤ x ≤ 0.4 have been synthesized using a conventional solid-state reaction method, and investigated experimentally and theoretically using first-principle calculations. Rietveld analyses of joint synchrotron X-ray and neutron diffraction patterns show the formation of a pure crystalline phase with cubic (F m3m) structure with partial ordering in the B-sites. The replacement of Fe by Sc leads to the increase of the cation order between the B and B sites. As the non-magnetic Sc 3+ ions replace the magnetic Fe 3+ cations, the antiferromagnetic state of PbFe 2/3 W 1/3 O3 is turned into a ferrimagnetic state reflecting the different magnitude of the magnetic moments on the B and B sites. The materials remain ferroelectric relaxors with increasing Sc content. Results from experiments on annealed and quenched samples show that the cooling rate after high temperature annealing controls the degree of cationic order in Pb(Fe1−xScx) 2/3 W 1/3 O3 and possibly also in the undoped PbFe 2/3 W 1/3 O3.

“…Short-range order (SRO) properties and pseudo-cubic phase down to 10 K were reported [1][2][3]. By forming solid solutions with PbTiO 3 (PT), the relaxor properties are shifted to ferroelectricity, the resulting system exhibiting excellent multifunctional properties [1,4]. The composition-induced transition from SRO relaxor to long-range order (LRO) ferroelectric and the possible magnetoelectric coupling are discussed here, using the results of the Raman and magnetic study of (1 − x)PbFe 2/3 W 1/3 O 3 -xPbTiO 3 ceramics.…”
