Diopside-magnetite; A novel nanocomposite for hyperthermia applications

In the present work, the releasing heat, scaffold apatite formation, and magnetic behavior of a novel diopside-magnetite nanocomposite with various contents of magnetite (Fe3O4) were evaluated. The N´eel and Brown relaxations did not have a significant effect on the specific absorption rate (SAR) of the composite samples. Indeed, magnetic saturation, Ms, indicated a crucial effect on the heat release of the samples. The sample with 30 wt% magnetite had the highest value of SAR, while the sample with 20 wt% magnetite, in the form of scaffold, allowed the high amount of apatite formation on its surface.
