© 2017 (1−x)Sr0.92La0.08TiO3-(x)CaMn0.98Nb0.02O3 (SLTO-CMNO) ceramics with x = 0, 0.1, 0.2 and 0.3 were prepared employing a solid state sintering method. X-ray diffraction patterns and X-ray absorption spectra from synchrotron light indicated the substitution of CMNO in SLTO ceramic. Upon CMNO addi...
