Electrical transport of 0.3Bi1-xYxFeO3-0.7Ba0.8Sr0.2TiO3 ceramics

Structure properties and dielectric relaxation of Ca0.1Na0.9Ti0.1Nb0.9O3 ceramic

“…The relaxor phenomenon has recently been explored in perovskite structure, viz. Ba 1− x Na x (Ti 0.8 Sn 0.2 ) 1− x NbO 3 , 46 (Pb 1−3 x /2 La x )(Mg 1/3 Nb 2/3 )O 3 , 47 0.3Bi 1− x Y x FeO 3 -0.7Ba 0.8 Sr 0.2 TiO 3 ( ref. 48 ) and (Pb 1−3 x /2 La x )(Zr 1− y Ti y )O 3 .…”

Dielectric, impedance and modulus spectroscopy of Pb(Zr0.52−x Ce x Ti0.48)O3 (x = 0.00, 0.10) ferroelectric ceramics

“…But the merger of ¢ Z at lower frequencies for modified PZT is due to the reduction of space charge polarization at low frequencies only. The higher values of resistance at low frequencies is due to the presence of all types polarizations of ceramics [27]. This section provides an insight into the electrical processes having the largest resistance in accordance with relations [28]…”

“…Also, the peaks are asymmetric and are shifting towards the region of high frequency due to the substitution of Ce +4 ions at the Zr +4 site. This means that electrical phenomenon is slow at the start due to the aggregation space charge ions [25,27]. The continuously varying peaks towards the high frequency region is attributed to the lowest capacitance of material due to Ce doping.…”
