“…The dielectric peak exhibits a strong frequency dependence with which confirms pronounced relaxor-ferroelectric behavior [26]. This behavior can also be described by the degree of diffuseness (g) using a modified Curie-Weiss law [15]. The inset of Fig.…”

“…Since it is believed that the ferroelectricity of perovskite-based compounds arises mainly from the distortion of BO 6 octahedra, the partial substitution of Mn 3þ (d 4 ) for Nb 5þ (d 0 ) on the Aurivillius B-site might improve the ferroelectric properties due to the effect of different ionic radii, as well as introducing a magnetic moment [12e14]. The substitution of Ln 3þ cations on the Aurivillius A-site has previously been shown to improve the dielectric and ferroelectric properties [15,16].…”

“…In recent years, dielectric capacitors have received much attention as promising materials for energy storage applications due to their high dielectric constant over a wide temperature range, low dielectric loss, large remnant polarization, low coercive fields, high electrical energy densities, and outstanding fatigue endurance, which are competitive with batteries and other power storage systems [1][2][3]. Due to the rapid development of the electronics industry, energy storage systems with enhanced properties are urgently required.…”

The double-layer Aurivillius phases Pb 1-2x Bi 1.5+2x La 0.5 Nb 2-x Mn x O 9 (x = 0, 0.1, 0.3, and 0.5) were synthesized by a molten salt method using a mixture of K 2 SO 4 /Na 2 SO 4 . The effect of composition on the structure, morphology and dielectric properties was investigated. X-ray diffraction showed that single-phase samples with a non-polar, orthorhombic A2 1 am structure were obtained for x = 0, 0.1 and 0.3. The unit cell becomes more orthorhombic with increasing x as the degree of distortion of the BO 6 octahedra in the perovskite layer increases. Raman spectroscopy showed the typical modes of the orthorhombic double-layer Aurivillius structure and indicated that the La 3+ ions prefer to occupy the perovskite A-site, Mn 3+ occupies the B-site, and the Pb 2+ ions are found in the Bi 2 O 2 layer. The morphology of the samples was probed by scanning electron microscopy, which showed anisotropic, plate-like crystallites that increased in size with increasing x. The dielectric constant significantly increased with x, and the ferroelectric properties became more relaxor-like.

“…The motion of oxygen vacancies and free electrons plays an important role in the variation of q dc of intergrowth BLSFs in the temperature range from 75 to 600°C [21,22]. As reported before, the bond strength of La-O is stronger than that of Bi-O [23,24]. La 3?…”

Structure and temperature dependence of electrical properties of Ca(Bi,La) 4 Ti 4 O 15 -(Bi,La) 4 Ti 3 O 12 (CBT-BIT-xLa) ceramics were studied. With La 3? doping content increasing, the samples exhibited diffused dielectric constant anomalies, and the Curie temperature (T c ) decreased. Meanwhile, the dielectric loss of CBT-BITxLa was reduced. CBT-BIT-0.8La performed an improved piezoelectric constant (d 33 ) value of 23.4 pC/N and remained until the temperature increased to 500°C. In addition, CBT-BIT-0.8La performed an enhanced q dc value of 3.26 9 10 15 X cm, at room temperature. CBT-BIT-0.8La showed clearly higher dc resistivity (q dc ) than CBT-BIT, even with increasing the temperature to 600°C.
