A sensitive AC magnetometer using a resonant excitation coil for magnetic fluid characterization in nonlinear magnetization region

In order to tailor the magnetic nanoparticles (MNPs) properties for intended applications, it is crucial to unravelling their fundamental dynamics with respect to excitation magnetic field. In this work, we report on the development of a sensitive AC magnetometer using a resonant excitation coil for...
