To investigate the orbital glass physics coexistence with re-entrant structural transition in BiCuMn6O12 using inelastic neutron scattering

Abstract: The new solid solution in the quadrupole perovskite family, BiCuMn6O12 attracts considerable attention by producing a mixture of Mn3+ and Mn4+ which introduce charge degree of freedom. No evidence of long-range magnetic order was noticed down to 2 K in neutron diffraction study except the presence of short range ferromagnetic correlations. It shows re-entrant structural transition on cooling which is quite new in the family of quadrupole perovskites. But the underlying physics behind this peculiar behaviour is still to be explored and spin dynamics need to be investigated in detail. We propose here to perform inelastic neutron scattering experiment on the polycrystalline sample of BiCuMn6O12 to investigate the spin wave excitations which will deliver adequate information on spin-gap, crystal field anomalies and provide a microscopic picture of magnetic interactions pathways.
