Opis

This book presented here investigated distinctive physical properties of two main rare-earth based orthoferrites (SmFe1-xNixO and NdFe1-xNixO3) both in their bulk and thin film form. The aim is to develop functional materials that have potential applications in the storage and the spin based electronics, spintronic devices, where in the spin controlled electrical and magnetic properties area exploited. Investigation of the structural, optical, electric and dielectric properties of Ni doped (Nd/Sm)FeO3 orthoferrites are carried out in bulk form to understand the possible mechanism for their conduction and colossal dielectric constant.Thin films of these materials were characterized to comprehend crystallographic, Raman, morphological, electrical and magnetic transport properties. The effect of gamma and SHI irradiation on different physical properties of the films were also highlighted.
