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 (Fe3 O4 ) 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 30wt% magnetite had the highest value of SAR, while the sample with 20wt% magnetite, in the form of scaffold, allowed the high amount of apatite formation on its surface.
