High-Frequency and High-Field Hysteresis Loop Tracer for Magnetic Nanoparticle Characterization

Existing metrology tools for magnetic nanoparticles cannot generate magnetic fields of the necessary high strength at high frequency to determine particle saturation and coercivity at conditions representative of their use, for example, in composite inductor cores, medical imaging, and hyperthermia treatments for cancer. To address this measurement need, this letter presents the design of a high-f...
