Revived BBFTO double perovskite with improved dielectric properties for some possible device applications

Investigation of the structural, dielectric, magnetic properties and NTC-thermistor response of CaBiFeMnO6 double perovskites

“…The vibrations within the range of 850-400 cm À1 are correlated with the specific type of lattice. 23 In double-ordered perovskite materials, the existence of perovskite phases may be identified by detecting transmission bands at 874, 994, and 1405 cm À1 . 24 Since octahedral BO 6 is associated with a larger concentration of charge carriers, the prominent peaks at 506, 521, and 563 cm À1 may be ascribed to the symmetrical stretching of BiO 6 25,26 or the anti-symmetric oscillations of the MnO 6 and FeO 6 octahedrons.…”
