N2 - The study of magnetic susceptibility of the Bi2BaNi x Nb2-x O9-δ solid solutions has shown that paramagnetic nickel atoms are present in diluted solutions as exchange-bound dimers formed by Ni(III) atoms in the high-spin state and characterized by the exchange parameter J of 12 cm-1. As the concentration of the solid solutions increases, clusters consisting of pairs of ferromagnetic Ni(III) dimers with antiferromagnetic exchange type and J = -170 cm-1 are formed. © 2014 Pleiades Publishing, Ltd.
