“…From the slope of these straight lines and Eq. (9), the values of W m were calculated for the studied compositions and listed in Table. …”

Structural and Dielectric Properties of La0.33Sr0.67M0.33Ti0.67O3±δ (M = Mn or Fe) Perovskites

“…In this region, the curve becomes monotonous almost linear growing. This part of conductivity corresponds to the ac conductivity (σ ac ) which can be described by the following power law [31]: σ ac = Aω n (9) where A is the pre-exponential factor and n is the power law exponent. The exponent n represents the degree of interaction between mobile charge carriers with the lattice, and the coefficient A determines the strength of polarizability.…”

“…In order to improve the performance of dielectric oxide ABO 3 perovskite (BaTiO 3 , CaTiO 3 , SrTiO 3 ), partial ionic substitutions in A site (Ca, Ba, Sr) or B site (Ti) were performed. Consequently, new dielectric materials substituted perovskite and free of lead have been developed in recent years due to their interesting properties [5][6][7][8][9]. SrTiO 3 (STO) perovskite is very studied in the literature both for its structural properties, primarily used as a substrate for thin films, because of its lattice matching with the deposited layers, and for its dielectric properties.…”

The dielectric and electric properties of (Ba0.68−Sr0.311Bi0.006Mg )(Ti0.99Sn0.01)O3 ceramics

“…Many attentions have been paid to improve the dielectric properties of BaTiO 3 ceramic via partial substitution of either Ba-ions (Asite doping) or Ti-ions (B-site doping) [6]. So far, many new solid solutions with excellent properties have been developed, such as Ba 1−x Sr x TiO 3 [7], BaTi 1−x Sn x O 3 [8][9][10] and (BaSr)(SnTi)O 3 [11,12] ceramics. Among them, stannum-containing titanate ceramics (TS) exhibited promising dielectric properties [8][9][10][11][12][13][14][15][16][17][18][19].…”

Aldica et al [9] prepared dense Ba(Ti 1−x Sn x )O 3 (x = 0.13) ceramic by spark plasma sintering and suggested that the influence of degree of compositional disorder on the average transition temperature can be attributed to the disorder-related variation of the average diameter of the oxygen octahedral surrounding ferroelectric ions in the perovskite structure.…”
