Multiferroic ceramic solid solutions between the ferroelectric relaxor Pb(Fe2/3W1/3)O3 (PFW) and "normal" ferroelectric PbTiO3 (PT) - PFW-PT have been synthesized by a modified B-site precursor method and characterized by microwave dielectric measure

Donor doping is commonly applied for softening of the piezoelectric and dielectric properties and facilitation of polarization switching in the ubiquitous Pb(Zr,Ti)O3 [PZT] ceramics. The origin of the donor-dopant effects is not entirely clear. (Pb,B

Conductive domain walls (DWs) in ferroic oxides as device elements are a highly attractive research topic because of their robust and agile response to electric field. Charged DWs possessing metallic-type conductivity hold the highest promises in thi

Thin epitaxial films have a great potential to be used in real life applications, such as oxide-on-silicon. However, they often contain a large amount of defects, leading to an enhanced electrical conductivity. This could be desirable in some applica

Magnetic, electric and mechanical properties can be strongly coupled in multiferroic materials. However, only few models were developed to describe electro-magneto-mechanical coupling effects on them. We report the influence of the strain induced pha

The co-existence of ferroelectric and ferromagnetic properties at room temperature is very rarely observed. In multiferroics, microscopic coupling interaction between the ferroelectric and magnetic order results in the macroscopic correlation between

Relaxor–normal transition in ferroelectric materials have been extensively studied through their optical and dielectric properties. However, only few reports concerning simultaneously elastic and dielectric characterization were presented. In this

Presented here are the results of magnetic data that reveal that both Pb-based perovskites samples, Pb(Fe1/2Nb1/2)O3 (lead iron niobate – PFN) and Pb(Fe2/3W1/3)O3 (lead iron tungstate – PFW), exhibit a change in magnetic ordering from paramagneti

Dielectric and magnetic properties were investigated in Pb(Fe2/3W1/3)O3–PbTiO3 ceramics. The dielectric constant in these materials exhibits changes at the magnetic ordering temperature, which presents a close connection with the magnetoelectric in

Magnetoelectric coupling can be observed in multiferroic materials in the regions where magnetic and ferroelectric ordering coexist and in many cases is mediated via lattice strain. Pb(Fe 1/2 Nb 1/2 )O 3 (PFN) is a well-known multiferroic, presenting
