Understanding the structural, optical, and dielectric characteristics of SrLaLiTe1−x Mn x O6 perovskites

Abstract In electronic applications, good dielectric permittivity material has huge potential in the capacitive energy storage devices. Herein, in the present work the dielectric study of SrLaLiTe1−x Mn x O6 (x = 0.02, 0.04, 0.06, 0.08, and 0.10) double perovskites has been studied and discussed. Th...
