The HNPs were prepared by growing Au nanoparticles (AuNPs) Nanoparticles with an average diameter of 3 nm on the surface of Fe O magnetic nanoparticles (MNPs) with an average diameter 3 4 Hybrid of 10 nm. The structural properties were determined by transmission electron microscopy (TEM), dynamic light RF solenoid coil scattering (DLS), and X-ray diﬀraction (XRD). Under the AMF, the initial heating rate of the HNPs solution was lower Alternating magnetic ﬁeld than that of the MNPs solution because HNPs have a reduced saturation magnetization
