The work deals with the study of the phase composition and crystal structure of new mixed ferrites Pr0,5R0,5FeO3 (R = Nd, Gd, Tb, Dy, Ho) obtained by solid state reactions technique. It was established that all samples synthesized adopt orthorhombic perovskite structure isotypic with GdFeO3. Unit cell dimensions and atomic coordinates of the mixed rare earth ferrites derived by full profile Rietveld refinement technique agree well with the data of the “pure” PrFeO3 and RFeO3 compounds, thus proving formation of continuous solid solutions Pr1-xRxFeO3 in the PrFeO3 —RFeO3 systems (R = Nd, Gd, Tb, Dy, Ho)
