High permittivity and low dielectric loss analysis of lead free Sr1-xLax(Ti0.5Fe0.5)O3M. R. Shah1, A. K. M. Akther Hossain2(1. Department of Physics, Primeasia University, Banani, Dhaka-1213... permittivity (about 104) and low dielectric loss (about 10-3). SLTFO also display minimum dielectric loss within the lower and higher limits of frequency, indicating that the samples are of good quality......
Hole-pinned defect-dipoles induced colossal permittivity in Bi doped SrTiO3 ceramics with Sr deficiencyYulong Qiao1,Weili Li1,2,Yulei Zhang1,Lu Jing1,Chang Gao1,Wenping Cao3,Dan Xu4,Weidong Fei1,51...), were prepared via conventional solid-state reaction route. A colossal permittivity(CP) over 104 with low dielectric loss less than 0.05 was obtained in x=0.05 Sr1-1.5 xBixTiO3 ceramics. In addition......
