“…A non-isovalent dilution on the B-site affects the LRO as well as the ground state 17 . We establish that as long as the dilution is isovalent, the non-magnetic ions do not produce a strong effect on the magnetic phase transitions in this family.…”

“…To date, the role played by non-magnetic ions in formation of AFSG state in these perovskites remains unclear. Previous studies of PFN diluted by non-isovalent Ti 4+ at the Fe/Nb site or by isovalent Ba 2+ at the Pb site suggested that its magnetic properties are indeed strongly affected by the type of non-magnetic ion in the lattice 17 . In the present work we make the next logical step and focus on the fully substituted stoichiometric lead iron tantalate, PbFe 1/2 Ta 1/2 O 3 (PFT ), a close relative of PFN .…”

Magnetic short- and long-range order inPbFe0.5Ta0.5O3

PbFe 1/2 Ta 1/2 O3 belongs to the family of PbB x B 1−x O3 which have inherent chemical disorder at the B-site. Due to this disorder, a complex magnetic phase diagram is expected in the material. In this paper, we report experimental results of magnetic properties of PFT through macroscopic characterization, neutron scattering and Mössbauer spectroscopy techniques. With these results we show for the first time that PbFe 1/2 Ta 1/2 O3 behaves very similar to PbFe 1/2 Nb 1/2 O3 , i.e, it undergoes AF transition at 153 K and has a spinglass transition at 10 K, below which the antiferromagnetism coexists with spinglass. We suggest that the mechanism which is responsible for such a non-trivial ground state can be explained by a speromagnet-like spin arrangement similar to the one proposed for PbFe 1/2 Nb 1/2 O3 .

For Pb(Fe0.5Nb0.5)O3 the χ(T ) and m(H) measurements up to 70 kOe were performed with the aim to estimate the antiferromagnetic (AFM) and superantiferromagnetic (SAF) contribution to χ(T ). Below TN the increase of χ(T ) is attributed to a small part of Fe 3+ ions in the SAF clusters. For high elds the suppression of the AFM and enhancement of the SAF susceptibility was observed. An inection point of the m(H) curves below the Néel point suggests the presence of a spin reorientation process connected with the AFM phase.

Elastic and anelastic relaxation behaviour of perovskite multiferroics I: PbZr0.53Ti0.47O3 (PZT)–PbFe0.5Nb0.5O3 (PFN)

Perovskites in the ternary system PbTiO 3 (PT)-PbZrO 3 (PZ)-Pb(Fe 0.5 Nb 0.5 )O 3 (PFN) have attracted close interest because they can display simultaneous ferroelectric, magnetic and ferroelastic properties. Those with the most sensitive response to external fields are likely to have compositions near the morphotropic phase boundary (MPB) which lies close to the binary join Pb(Zr 0.53 Ti 0.47 )O 3 (PZT)-PFN. In the present study, the strength and dynamics of strain coupling behaviour which accompanies the development of ferroelectricity and (anti)ferromagnetism in ceramic PZT-PFN samples have been investigated by resonant ultrasound spectroscopy. Elastic softening ahead of the cubic-tetragonal transition does not fit with models based on dispersion of the soft mode or relaxor characteristics but is attributed, instead, to coupling between acoustic modes and a central peak mode from correlated relaxations and/or microstructure dynamics. Softening of the shear modulus through the transition by up to *50 % fits with the expected pattern for linear/quadratic strain/order parameter coupling at an improper ferroelastic transition and close to tricritical evolution for the order parameter. Superattenuation of acoustic resonances in a temperature interval of *100 K below the transition point is indicative of mobile ferroelastic twin walls. By way of contrast, the first-order tetragonalmonoclinic transition involves only a small change in the shear modulus and is not accompanied by significant changes in acoustic dissipation.

No evidence of magnetoelastic coupling has been found, in spite of the samples displaying ferromagnetism below *550 K and possible spin glass ordering below *50 K. For the important multiferroic perovskite ceramics with compositions close to the MPB of ternary PT-PZ-PFN, there must be some focus in future on the role of strain heterogeneity.
