摘要：

In the present work, LaFeO3 and YFeO3 orthoferrites were carefully prepared using the solid state high temperature ceramic and sintering technique. On these two materials, numerous measurements were applied before and after gamma-absorbed dose (1.24 Mrad) namely, X-ray diffraction (XRD), DC-electrical conductivity, UV/Vis, IR, Mossbauer effect and EPR. Results obtained were explained, interpreted, and discussed in detail on the basis of lattice structure of the new perovskite investigated and the interaction of gamma-radiation with the investigated materials. Finally, the gamma-induced functions are evaluated for electrical conduction, Mossbauer effect and EPR for the first time.
