“…[8][9][10]. The ferroelectric and dielectric properties of Sm-and La-codoped, Eu-, Mn-, and Nd-doped BiT thin films are observed by Du et al [11] Pei et al [12] Li et al [13] of Nd-substituted BiT nanoparticles (NPs) by Marikani et al [14] and of Zr-doped BiT ceramic by Subohi et al [15] To our knowledge, there are not so many experimental works which report multiferroism in BiT. Multiferroism, that is, the simultaneous existence of ferroelectricity and ferromagnetism in one and the same phase, is observed by substitution of Ti with Fe, Co, or Mn ions in bulk BiT.…”

Based on a microscopic model and the Green’s function theory we have investigated the temperature, size, magnetic field and ion doping dependence of the magnetic, electric and dielectric properties in Fe‐and Nd‐doped ferroelectric Bi4Ti3O12‐bulk and nanoparticles. The multiferroisms can be achieved in two ways. At once the magnetism appears by substitution of the nonmagnetic Ti4+ ion with Fe3+, or other transition metal ions in bulk Bi4Ti3O12. Otherwise, the simultaneous existence of Fe3+ and Fe4+ giving rise to a super‐exchangenism responsible for the ferromagnetic interaction. Moreover, multiferoism is possible also in pure Bi4Ti3O12 nanoparticles. Due to surface effects and oxygen vacancies leading to different valence states on the surface of Ti3+ or Ti2+ with spin value S≠0 there appears weak magnetism, which can be improved by Fe ion doping. We demonstrate that doping with rare earth ions, for example Nd3+, at the Bi3+ site is able to improve the ferroelectric, multiferroic and dielectric properties.This article is protected by copyright.

“…As a comparison, the La-PMN-PT thin films were investigated, because there is no energy level in the 4f energy layer of La 3+ ion. In previous work, La 3+ ion can be used to improve the ferroelectric and dielectric properties in RE doped ferroelectric thin films with strong photoluminescence properties [45]. Figure 5(b) shows the excitation spectrum monitoring at 668 nm and emission spectrum excited at 431 nm.…”

Rare earth (RE = La3+, Sm3+, Pr3+) ion doped Pb(Mg1/3Nb2/3)O3-PbTiO3 (RE-PMN-PT) ferroelectric thin films with compositions near the morphotropic phase boundary were grown on the Pt/TiO2/SiO2/Si(100) substrate using sol-gel/spin coating method. The phase structure, electrical properties, and photoluminescence performance of thin films were investigated systematically. The highly (100)-preferred orientation was obtained in pure perovskite Sm-PMN-0.30PT thin films with an average grain size of 131 nm. After 2.5% Sm3+ doping, the PMN-0.30PT thin films exhibited a triple enhancement of dielectric permittivity with a maximum value of 3500 at 1 kHz, a low dielectric loss of 1.3%, and high remanent polarization of 17.5 μC/cm2 at room temperature. In visible light and near-infrared band, the transmittance rate increased with PT content and showed the highest value of 85% in 2.5%Sm-PMN-0.31PT. In addition, the films presented strong red-orange emission at 599 nm, which was sensitively in temperature range of 248–273 K corresponding to the rhombohedral to monoclinic phase transition temperature.

Lead-free films of Bi4-xNdxTi3O12 were deposited on Pt(111)/Ti/SiO2/Si(100) substrate via spin-coating methods. It is shown that there are no secondary phases in Bi4-xNdxTi3O12 films and clear interfaces between the Bi4-xNdxTi3O12 films and substrates when the films are annealed at 700 ℃. And the Bi4-xNdxTi3O12 films also exhibit a blue light emission peak at 437 nm and a yellow light emission peak at 580 nm. There are narrower band gaps, higher dielectric constant and lower dielectric loss when Nd 3+ concentration varies from 0 to 0.85. And the Bi3.15Nd0.85Ti3O12 film possesses the minimum of band gap energy (2.67 eV). Moreover, Bi3.55Nd0.45Ti3O12 film exhibits a minimal leakage current density and a maximal remanent polarization, which is highly beneficial for the potential applications in multi-functional devices.
