Multiferroic properties of Bi5.75R0.25Fe1.4Ni0.6Ti3O18 (R =Eu,Sm,Nd,Bi and La) ceramics
文献摘要：
An improved technique was used to prepare the ceramic samples of Bi5.75R0.25Fe1.4Ni0.6Ti3O18 (BRFNT,R =Eu,Sm,Nd,Bi,and La).The five-layer Aurivillius phase of the samples was confirmed by X-ray diffraction (XRD) without detectable impurities.BRFNT samples exhibit the pseudo-tetragonal except the orthorhombic BSmFNT samples.The characteristic plate-like morphology was revealed by field emission transmission electron microscopy (FETEM) images.At ambient temperature,all the samples present both ferroelectric and magnetic properties and BEuFNT shows the best ferroelectric behavior with its rema-nent polarization as high as 14.9 μC/cm2 under 155 kV/cm,which is three times higher than that of Bi6Fe1.4Ni0.6Ti3O18.Moreover,the remanent magnetization of BEuFNT is increased up to 1.20 emu/g compared to that of Bi6Fe1.4Ni0.6Ti3O18 which is only 0.53 emu/g.With increasing radius of the intro-duced A-site ions,the ferroelectric phase transition temperature (TCE) is decreased while the magnetic phase transition temperature (TCM) fluctuates.The decrease in both TCE and TCM corresponds to the upward shift of the related Raman modes and vice versa,indicating that the TCE and the TCM depend not only on the t factor,but also on the strength of the covalent bonds.
