Approaching the true ground state of frustrated A-site spinels: A combined magnetization and polarized neutron scattering study

, macroscopic measurements evidence a ”cusp” in zero field-cooled susceptibility around13 K. Dynamic magnetic susceptibility and memory effect experiments provide results that do notconform with a canonical spin-glass scenario in this material. Through polarized neutron scatteringstudies, absence of long-range magnetic order down to 4 K is confirmed in FeAl

Field-induced self-assembly of iron oxide nanoparticles investigated using small-angle neutron scattering

The magnetic-field-induced assembly of magnetic nanoparticles (NPs) provides a unique and flexible strategy in the design and fabrication of functional nanostructures and devices. We have investigated the field-induced self-assembly of core-shell iron oxide NPs dispersed in toluene by means of small-angle neutron scattering (SANS). The form factor of the core-shell NPs was characterized and analyzed using SANS with polarized neutrons. Large-scale aggregates of iron oxide NPs formed above 0.02 T as indicated by very-small-angle neutron scattering measurements. A three-dimensional long-range ordered superlattice of iron oxide NPs was revealed under the application of a moderate magnetic field. The crystal structure of the superlattice has been identified to be face-centred cubic.
