- Аннотация: Bismuth vanadate Bi4V2O11?y doped with Fe was studied by neutron diffraction. It was shown that Fe substitutes V only partially and the redundant iron forms an impurity hematite phase. In the sample with nominal content Bi4(V0.96Fe0.04)2O11?ya new phase transition within the frame of the monoclinic structure with the appearing of inversion center was discovered in the temperature region 200–3008C. This transition was also confirmed by DTA experiments. Slow stabilization of the crystal structure with stabilization times of the order of hours, accompanied by a decrease of the unit cell volume,wasobserved.AthighlevelofFedoping,inadditionto thedominanttetragonal g-phase someamount ofthe nanosized monoclinic a-phase was detected.
