Abstract

Author(s): Meng, D; Xiao, Y; He, H; Liao, Y; Zhang, H; Zhai, J; Chen, Z; Martin, LW; Bai, F | Abstract: We report the pulsed-laser deposition of epitaxial double-perovskite Bi2FeCrO6(BFCO) films on the (001)-, (110), and (111)-oriented single-crystal SrTiO3 substrates. All of the BFCO films with various orientations show the 1/2 1/2 1/2 and 3/2 3/2 3/2 superlattice-diffraction peaks. The intensity ratios between the 1/2 1/2 1/2-superlattice and the main 111-diffraction peak can be tailored by simply adjusting the laser repetition rate and substrate temperature, reaching up to 4.4%. However, both optical absorption spectra and magnetic measurements evidence that the strong superlattice peaks are not correlated with the B-site Fe3+/Cr3+ cation ordering. Instead, the epitaxial (111)-oriented Bi2FeCrO6 films show an enhanced remanent polarization of 92nμC/cm2 at 10nK, much larger than the predicted values by density-functional theory calculations. Positive-up-negative-down (PUND) measurements with a time interval of 10nμs further support these observations. Therefore, our experimental results reveal that the strong superlattice peaks may come from A- or B-site cation shifts along the pseudo-cubic [111] direction, which further enhance the ferroelectric polarization of the BFCO thin films.

Abstract

In the present work, the Li0.43Zn0.27Ti0.13Fe2.17O4 ferrite, a low temperature sintered gyromagnetic material, was prepared via solid-state reaction method. A pure spinel phase can be formed with a sintering temperature ranging from 880°C to 920°C, which allows them to be co-fired with silver. The addition of ZnO–Bi2O3–SiO2 (ZBS) glass in the Li0.43Zn0.27Ti0.13Fe2.17O4 ferrites contributes significantly to the grain growth and ferromagnetic properties through a low temperature (~900°C) sintering process. Results show that the addition of ZBS glass (0.125–2.00 wt%) cannot only double saturation induction (from ~150 to 300 mT) but also drastically reduce ferromagnetic resonance line width at 9.3 GHz (from 920 to 228 Oe), indicating that ZBS glass is a good candidate for lowing the sintering temperature of LiZnTi ferrites.
