Magnetic Domain Texture in Fe<sub>3</sub>O<sub>4</sub> Thin Films on SiO<sub>2</sub> Nanospheres. [PDF]
Fe3O4 thin films grown on ordered SiO2 nanospheres form curved nanocaps with 3D geometry, inducing magnetic domain texture. X‐ray spectromicroscopy (XMCD‐PEEM), cross‐sectional electron microscopy (STEM), and polarized grazing‐incidence small‐angle neutron scattering (GISANS) reveal how topography modulates magnetization.

The effect of ions doping on the rheological properties of ferrite ferrofluids
A series of ferrite nanoparticles were synthesized via ion doping and then were coated by surfactant and dispersed in perfluorinated polyether oil (PFPE-oil), and the various ferrite ferrofluids were obtained. The scanning electron microscope was used to

The Investigation of Mixed Ferrofluids Containing Iron Oxide nanoparticles and Microspheres
The aim of the present work is the synthesis and characterization of iron oxide (Fe3O4) nanoparticles. These nanoparticles are coated with oleic acid and polyvinyl butyral and mixed with microspheres and further developed ferrofluids with silicon oil ...

Ferrofluid Leidenfrost droplets [PDF]
We experimentally investigate the behavior of ferrofluid Leidenfrost droplets subject to a magnetic field gradient. As a droplet evaporates, it experiences a bouncing instability and finally takes off when its radius reaches a critical value.

Pattern formation in quantum ferrofluids: From supersolids to superglasses
Pattern formation is a ubiquitous phenomenon observed in nonlinear and out-of-equilibrium systems. In equilibrium, quantum ferrofluids formed from ultracold atoms were recently shown to spontaneously develop coherent density patterns, manifesting a ...
