Evidence of finite magneto-electric coupling in SmFeO3 – PbTiO3 solid solutions

Abstract

Present work investigates the detailed multiferroic properties of Pb1-xSmxTi1-xFexO3, (x = 0.21, 0.22, 0.23, 0.24 and 0.25) synthesize through solid state reaction route. The structural, dielectric, ferroelectric and magnetic properties were measured. A sincere study is carried out to detect the magneto-electric coupling in all the samples through magneto-dielectric, magnetization after electric poling and magneto-pe response. The maximum value of coupling coefficient (γ) and magneto-dielectric response (MDR) of sample x = 0.24 has shown by magneto-dielectric properties and magnetization after electric poling whereas magneto-pe has shown that all the samples possess multiferroic nature.

Existence of Magneto-Resistance and Magneto-Dielectric Effect in Composite of Perovskite Pb0.79Nd0.21TiO3 and Sr -Based U-Type Hexaferrite (Sr1–3xNd2x)4Co2Fe36O60

“…[12][13][14] Several studies have been done in this approach where PbTiO 3 -ReFeO 3 have been analyzed for its magnetoelectric coupling within the single structure. [15][16][17] From the literature survey, we have found that PbTiO 3 shows 11.56%, 13.09% and 33.7% change in the dielectric constant when doped with PrFeO 3, SmFeO 3 and NdFeO 3 respectively. Therefore, Nd doped PT has been decided for the perovskite part.…”

“…Owing to its high Curie point, which also relies on composition, high electric resistivity, high magnetic permeability, low dielectric loss, superior chemical stability, and heat treatment of the samples, Sr-hexaferrites are among the most adaptable and materials that are appropriate for both low-frequency and high-frequency equipment are used. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] It is worth mentioning that the Interface of particles or grain does play important role in these kinds of composites in nano particles based thin films. The required correlation of charge, spin, orbital, and lattice freedom degrees frequently puts demanding constraints on deposition circumstances, and interface engineering in complicated oxide thin films has inspired several novel room-temperature functions.…”
