Evolving spin periodicity and lock-in transition in the frustrated ordered ilmenite-type β-Mn 2 InSbO 6
Abstract : Polar magnets are promising materials for new applications as multiferroics or in spintronics. In double corundum-related oxides, the cation ordering imposes a polar structure and the use of high pressure facilitates the insertion of magnetic cations into the compounds. Here we present the high-pressure synthesis of a new polar and ferrimagnetic corundum derivative Mn 2 InSbO 6 , which adopts the ordered-ilmenite-type structure. Neutron powder diffraction reveals that the high-temperature nearly collinear ferrimagnetic phase evolves to an incommensurate helical structure with k δ = [0 0 k z ] propagation vector, which then locks to the commensurate value of k z = 1/8. This complex magnetic behavior is likely to be related to magnetic frustration and the polar nature of the ordered double corundum structure.
