Phase transitions and magnetic properties of BiNb1-xFexO4-δ

Magnetic susceptibility of the iron-containing solid solutions BiNb1-xFexO4-delta in orthorhombic and triclinic modifications has been studied. The reversibility of the phase transition from the high-temperature triclinic modification to the orthorhombic one has been revealed by means of magnetic dilution and X-ray phase analysis by the example of polycrystalline samples of the solid solutions BiNb1-xFexO4-delta.
