Effect of Substitution in the Heating Efficiency of CuFe2O4 Nanoparticles for Magnetic Hyperthermia Application

Superparamagnetic nanoparticles have undergone detailed research for decades and have been investigated for potential use in magnetic hyperthermia and certain other biomedical applications. In this work, we have synthesized Cobalt-substituted CuFe

The structural properties of the samples are studied using X-ray diffractometer, Fourier Transform Infrared Spectroscopy, and Energy dispersive X-ray technique. To validate the possible suitability of the fabricated samples in magnetic hyperthermia application, magnetic and induction heating analysis is also performed. Comparing the computed specific absorption rates for each sample, it can be shown that Cu
