# comparison of internal magnetic domain structure in three magnetic nanoparticles

## Appears In

                        - Metrology of Magnetic Materials

Magnetic scattering contributions, (blue) parallel and (red) perpendicular, to the guide magnetic field with respect to the polarized beam small angle neutron scattering (PASANS) data of: A) BNF; B) JHU; and, C) nanomag-D-spio (SPIO) nanoparticles in D2O at room temperature. The fit shown uses models described in the article and illustrated in schematic diagrams. Domain structures of: D) BNF; E) JHU; and, F) nanomag-D-spio particles obtained from analysis and modeling PASANS data. Error bars (1σ) may be smaller than the symbol. Note: scattered neutron intensity from JHU and nanomag-D-spio particles is lower than from BNF particles.
