The use of microwave-assisted synthesis (in water) α-Fe2O3 nanomaterials followed by their transformation onto iron oxide Fe3O4-γ-Fe2O3 hollow nanoparticles encoding well-defined sizes and shapes [nanorings (NRs) nanotubes (NTs)] is henceforth described. impact experimental variables such as concentration reactants, volume solvent employed, reaction times/temperatures during the shape-controlled revealed that key factor gated generation morphologically diverse was associated to initial...
The generation of topological magnetic vortex-domain structures in iron-oxide nanomaterials has promising applications biomedical scenarios, such as heat generators for hyperthermia treatments. In this report we describe alternative kinds magnetic-vortex nanoparticles, circular ${\mathrm{Fe}}_{3}{\mathrm{O}}_{4}$ nanodiscs (NDs), and dissect their heating properties by in-depth investigation shape size, stoichiometry, orientations, switching field ``${H}_{S}$'' behaviors, through experiments...
Theoretical and micromagnetic simulation studies of magnetic nanospheres with vortex configurations suggest that such nanostructured materials have technological advantages over conventional nanosystems for applications based on high-power-rate absorption subsequent emission. However, full experimental evidence in spheres submicrometer size is still lacking. Here, we report the microwave irradiation fabrication Fe3O4 establish their configuration results, theoretical analysis, simulations....

Recent reports on spin structures produced in nanomaterials due to confinement of spins imposed by geometrical restrictions are at the center rising scientific interest. Topological curling magnetic (vortices) exhibit unique properties, regarding energy profile, good colloidal stability suspensions, manipulation under a low-frequency field, and torque exertion. The last property provides potential mechanically eradicate cancer cells via magnetomechanical actuation using remote ac fields....
