Short range magnetic order in the compositionally modulated Bi2Cr4/3Ni2/3O6 perovskite.

DOI

It is particularly challenging to synthesize a novel multiferroic material as it seems that the mechanisms that allow ferromagnets and ferroelectrics to work are mutually exclusive. With knowledge of the G-type antiferromagnetically ordered BiCrO3 and disproportionated BiNiO3 perovskites we have synthesized the new compound Bi2Cr1.3Ni0.7O6 which is related to the phase Bi2Mn4/3Ni2/3O6.Whilst we have a great deal of structural information, the magnetic ground state of Bi2Cr1.3Ni0.7O6 is less clear. There is not observation of any long range order by neutron powder diffraction although the effective moment in the paramagnetic regime is ~4.7 Bohr magnetons at 300K, and a transition and ZFC/FC divergence is observed at 25K. In order to elucidate any short range magnetic order, MuSR is an ideal technique to investigate the material with.
