Solid solutions of the (1 – x)BiFeO3– xNdCoO3system were synthesized by a solid-state reactions method. Peculiarities of the influence of isovalent substitution in BiFeO3of Bi 3+ , Fe 3+ ions by Nd 3+ , Со 3+ ions on the crystal structure, magnetization and thermal expansion of the forming solid solutions Bi1−xNdxFe1−xCoxO3are fixed. It is shown that the substitution up to 2% of Bi 3+ , Fe 3+ ions in BiFeO3by Nd 3+ , Со 3+ ions leads only to the partial destruction of the antiferromagnetic ordering of the Fe 3+ ions magnetic moments. According to the results of the magnetic properties investigation it is found that magnetic properties of the samples Bi1−xNdxFe1−xCoxO3(0.05 ≤ х ≤0.15) are due to the coexistence of the antiferromagnetic and ferromagnetic phases but the samples Bi1−xNdxFe1−xCoxO3(0.80 ≤ х ≤1.0) reveal paramagnetic properties.
