Magnetic field induced long-range ordering in magnetic nanoparticle 2D-superlattices: A POL-GISANS study at the free liquid interface
The understanding of self-assembly of nanoparticles into large area, defect free 2D-superlattices is of big interest for fundamental science as well as for creating a plethora of functional devices with enhanced collective properties. The understanding and tuning of interparticle interaction parameters, such as, surfactant shell interaction, particle size dependant effects and magnetic interaction between magnetic particles are of key to understanding the process and creating new devices. We are interested in the self-assembly of magnetic nanoparticles at the free liquid surface and the potential long-range ordering effects of an applied magnetic field. We aim to investigate this with Polarized Grazing Incidence Small Angle Scattering(POL-GISANS) in situ in a Langmuir trough environment at SuperAdam, taking full use of the incoming beam by a switch of sample orientation from vertical to horizontal. We propose to study 2D-superlattice formation with and without an imposed magnetic field at different surface pressures at a free liquid surface. In total, we ask for 6 days of beam time at SuperAdam
