The magnetic and electric properties of PZT-PFW-PFN ceramics

Magnetic skin effect in Pb(Fe _{1/2}$ Nb _{1/2}$ )O3

“…Whilst there has been some debate in the literature over the relaxor nature of PFN [55], it typically displays broadened dielectric properties similar to those for PMN and PZN [56][57][58][59], undergoes a ferroelectric transition at ∼400 K [60,61] and displays spatially short-range polar correlations similar to the polar nanoregions in PMN and PZN [17]. This suggests that it shares much of the fundamental physics of more standard relaxor materials and also underlies the sensitivity to composition which will be discussed specifically in this paper.…”

Fast broadband cluster spin-glass dynamics in PbFe1/2Nb1/2O3

“…PFN is a relaxor ferroelectric with similar dielectric properties to those for PMN and PZN discussed above [55,56], undergoing a ferroelectric transition at ∼400 K and displaying spatially short-range polar correlations similar to the polar nanoregions in PMN and PZN [19]. Interest in PFN originates from efforts in multiferroics [57][58][59] where strong coupling between ferromagnetism and ferroelectricity is sought, affording external control of either magnetic or ferroelectric domains.…”

“…In this regard, from the past few decades, there have been many attempts to improve the multiferroic properties of PFW by substituting or by making solid solutions with PFN, PbTiO 3 , etc. [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. However, by making these solid solutions and substitutions, there were new difficulties like inducing the space charges, and reducing the T N below the RT, and it rendered to normal ferroelectric behavior.…”
