Nanoscale Mapping of Internal Magnetization Dynamics Reveals How Disorder Shapes Heat Generation in Magnetic Particle Hyperthermia

Abstract Magnetic particle hyperthermia relies on the efficient conversion of magnetic field energy into heat, yet the microscopic mechanisms governing this process within individual particles remain poorly understood. Here, we combine AC magnetometry experiments with dynamic mic...

Reduced vortex descriptors linking polycrystallinity in magnetic nanoparticles with polarized magnetic small-angle neutron scattering

Analytical vortex models reduce polarized magnetic small-angle neutron scattering (SANS) from nanoparticle ensembles to a small set of texture descriptors. In this work, we apply this reduction to micromagnetic simulations of polycrystalline iron oxide nanoflowers at a fixed part...
