(Pr0.55Ca0.45)(Mn1−yCry)O3 (with y = 0.00, 0.03 and 0.06) have been prepared by means of a solid-state reaction from stoichiometric powder mixtures of binary oxides. XRPD reveals the formation of the perovskite-type compound for the whole compositions; no evidence for secondary phases may be detected. The structural refinements have been carried out using XRPD data applying the Rietveld method; the lattice parameters of the orthorhombic cell faintly change with composition. On the contrary the tilting of the octahedra results strongly dependent on the concentration of Cr in the 4b site. DC magnetic measurements have been performed as a function of temperature and magnetic field.
