Magnetic structure of the multiferroic kagome staircase compound (Co0.1Ni0.9)3V2O8 under magnetic field
The aim of the proposed experiment is to study the magnetic structure of multiferroic (Co0.1Ni0.9)3V2O8 under magnetic field. The pure Co and pure Ni compounds exhibit substantially different magnetic phase transition sequences and magnetic structures. The partial substitution of one ion by the other again brings new magnetic properties. Surprisingly, doping a small percentage of Co into the pure Ni compound stabilizes the multiferroic phase down to low temperature. We have studied the magnetic structures in (Co0.1Ni0.9)3V2O8 at zero field which differ from those in Ni3V2O8. Bulk magnetization data reveal a field dependent magnetic phase transition from the low-temperature incommensurate phase into a supposedly canted antiferromagnet phase. From our present knowledge we assume that the magnetic structure of this canted phase has to be different from the one in the pure Ni compound. We propose to study this magnetic structure in detail. Furthermore, field and temperature dependent studies of representative magnetic reflections should be carried out across the different magnetic phase transitions.
