摘要：

In this work structural, magnetic and electrical properties of R0.7Ca0.3Mn0.95Fe0.05O3 (R= Pr and Nd) perovskite manganites are presented. Structural characterization of these compounds shows that both have orthorhombic (Pbmn) phase. The Mossbauer spectra show clear evidence of the local structural distortion of the Mn(Fe)O-6 octahedron on the basis of non-zero nuclear quadrupole interactions for high-spin Fe3+ ions. It was found that the local structural distortion decreases significantly with replacing Pr3+ by Nd3+. This replacing dependence of the Jahn-Teller coupling strength estimated from the Mossbauer results was found to be consistent with the electrical and magnetic properties.
