Coercivity-size map of magnetic nanoflowers: spin disorder tunes the vortex reversal mechanism and tailors the hyperthermia sweet spot
Elizabeth M Jefremovas, Lisa Calus, Jonathan Leliaert
Iron-oxide nanoflowers (NFs) are one of the most efficient nanoheaters for magnetic hyperthermia therapy (MHT). However, the physics underlying the spin texture of disordered iron-…

Micromagnetic structure of oxidized magnetite nanoparticles: sharp structural versus diffuse magnetic interface
Elizabeth M. Jefremovas, Michael P. Adams, Lucía Gandarias +4
The oxidation of magnetite to maghemite is a naturally occurring process that leads to the degradation of the magnetic properties of magnetite nanoparticles. Despite being systemat…
