abstract = "Nanometric size Ca1-xGdxMnO3 (x = 0.05, 0.1, 0.15, 0.2) powder particles with perovskite-type structure were obtained by applying a modified glycine-nitrate procedure. [1, 2] All samples were investigated by X-ray diffraction (XRD), Infrared (IR) spectroscopy and EPR (electron paramagnetic resonance) measurements. In the perovskites with space group Pnma, octahedral tilting is most common and it is of great interest for geologists and materials science. It was experimentally observed how the amount of gadolinium dopants affects on the Mn-O bonds angles and distances, MnO6 octahedral tilting, the deformation due to the presence of Jahn-Teller distortion around the Mn3+ cation and relation between the structural and magnetic behavior. [3] The infrared reflection spectra of Ca1-xGdxMnO3 samples confirmed XRD results that Ca1-xGdxMnO3 nanopowders are of Pnma-1 structure and that the octahedral tilting is increased with Gd doping. The EPR spectra are in agreement with the expectation that EPR linewidth depend of Mn-O-Mn angle and that small octahedral tilting brought only a small change of the EPR linewidth.",
