ABSTRACT
The Bi0.85Nd0.15FeO3, BiFe0.85Mn0.15O3, and Bi0.85Nd0.15Fe0.85Mn0.15O3 ferrites solid solutions were synthesized and their crystal structure, magnetic susceptibility, thermal expansion, electrical conductivity, thermo-EMF and dielectric properties were studied. It was found that Bi0.85Nd0.15FeO3 and BiFe0.85Mn0.15O3 had rhombohedral structure (space group R3c), but Bi0.85Nd0.15Fe0.85Mn0.15O3 one had orthorhombic structure (space group Pnma) and all the complex oxides studied were the antiferromagnetic semiconductors of p-type, which electrical conductivity values were larger than for unsubstituted bismuth ferrite BiFeO3, Neel temperature and thermo-EMF coefficient sharply decreased at partial substitution of iron by manganese and linear thermal expansion coefficient values varied within (10.0鈥�13.4)鈥�10-6K-1. The values of charge carriers transfer parameters in (Bi,Nd)(Fe,Mn)O3 phases were calculated.
