Orthorhombic perovskites are nowadays broadly studied materials due to their tuneable magnetic and electric properties. Here we study NdFeO3 and PrMn1−xFexO3 bulk poly and monocrystals. They were prepared by floating zone technique from sintered powder oxides precursors in adequate stoichiometric amounts and their structure was determined by x-ray diffraction. Their optic and magneto-optic properties were obtained by spectroscopic ellipsometry and magneto-optic spectroscopy, providing full spectral permittivity tensor in extended visible range of energies.
