While being electrically insulating, magnetic insulators can behave as good spin conductors by carrying current with excited waves. So far, are utilized in multilayer heterostructures for optimizing transport or to form magnon valves reaching controls over the flow. In these studies, it remains an intensively visited topic what corresponding roles of coherent and incoherent magnons transmission...

The main objective of this research was to synthesize and characterize gold-coated Fe3O4 /SiO2 nanoshells for clinical applications. Magnetite nanoparticles (NPs) were prepared via co-precipitation. The results showed that smaller particles can be synthesized by decreasing the NaOH concentration, which in our case this corresponded to 35 nm by using 0.9 M of NaOH at 750 rpm. The NPs were then m...
