Magneto-orbital coupling in PbMn7-xFexO12
Abstract: The interplay between orbital order and magnetism in insulating manganites has been extensively studied following the seminal neutron diffraction experiments of Wollan and Koehler in the 1950s. Recently, we have shown that AMn7-xFexO12 quadruple perovskites display a novel magneto-orbital coupling of greater complexity than that previously observed, which we can explain through a universal model. Importantly, our model predicts coupling between orbital and magnetic degrees of freedom in all antiferromagnetic phases. However, if A =Pb, we have found an intermediate phase in which the coupling is destroyed. Further, by substituting Fe for Mn, the magneto-orbital ground state is suppressed altogether. Here, we propose a neutron diffraction experiment to solve the magnetic structure of PbMn0.69Fe0.1O12 in the decoupled phase, from which we will be able to refine our model.
