Dynamic Hysteresis Measurement of Magnetic Nanoparticles with Aligned Easy Axes
Journal of the Magnetics Society of Japan
Magnetic particle imaging (MPI) is a novel diagnostic imaging technique based on the use of magnetic nanoparticles (MNPs). Investigating the magnetic properties of magnetic nanoparticles is important for achieving a high spatial and temporal resolution in MPI. In this study, -Fe2O3 nanoparticles (core diameter: dc = 4 nm), Fe3O4 nanoparticles (dc = 20-30 nm), and Resovist ® were immobilized in a DC magnetic field with their easy axes aligned. DC and AC magnetization curves were measured fordoi:10.3379/msjmag.1803r009 fatcat:a5ncmgrs3reehbh2ovxpd3kt6q
