摘要：

Co-Zn ferrite nanoparticles have been investigated, aiming at a further improvement of the magnetic hyperthermia properties for bio-medical applications. We precisely tune the magnetic and the thermal properties of Co (x) Zn1-x Fe2O4 nanoparticles, prepared by using a high-temperature thermal-decomposition method, by chemically controlling the cation. The structure and the magnetic properties as well as the AC-heating characteristics of the synthesized Co (x) Zn1-x Fe2O4 were measured by using X-ray diffraction (XRD), vibrating sample magnetometer, magneTherm device and Mossbauer spectroscopy. The analysis of the XRD patterns confirmed the spinel phase, the crystalline size, and the lattice parameter. The magnetic behavior of Co-Zn ferrite was studied with M-H hysteresis curve measurements at room temperature. Also, the thermal properties were measured under an external applied field of 250 Oe at 112 kHz. In addition, we plasma-treated the samples with magnetic and thermal excellent characteristics for 30 min at room temperature. The cation distribution was investigated with Mossbauer spectroscopy and further analyzed with one sextet for the tetrahedral A site and four six-lines for the octahedral B-1, B-2, B-3, and B-4 sites.
