Magnetic lateral distribution of oxide thin film/ nanoparticles designed heterostructures for magnetic switching
Understanding the mechanisms of magnetization switching in nanosized systems is important for development of novel spintronic devices. In this project, we grow Fe3O4 films on nanosphere patterned substrates to achieve magnetization switching by the periodic curvature of the patterned substrate. Growing 30nm Fe3O4 thin films on 200nm SiO2 nanospheres, results in isolated Fe3O4 caps. The curvature of the caps affects the lateral correlations between the magnetic domains. In SQUID measurements, we observe differences in the in-plane MH curves which must be related to the geometry of Fe3O4 thin films grown on nanosphere-patterned substrate compared to a flat substrate. SQUID measurements, however, give only an average of the magnetic moment over the entire sample surface and cannot reveal the magnetic lateral ordering. Therefore, we propose to measure polarized GISANS to probe the depth-resolved lateral domain profiles of the isolated caps.
