[EN] The phase transition to perovskite-type structure, that occurs in some hexagonal manganites when foreign cations are incorporated into solid solution, has been studied. Several solid solution series belonging to the Y(Mn, Ni)O3, (Er, Ca)MnO3, (Y

The structural properties of solid solutions based on EuMnO3, in which Eu has been substituted by divalent Ca2+ and Mn by the divalent cation Ni2+ or the variable valence cation Co2+-Co3+ have been studied by X-ray diffraction (XRD) and X-ray absorpt
