摘要：
The structural, magnetic and ac magnetically induced heating characteristics of combustion synthesized MgFe2O4 nanoparticles have been investigated for application in magnetic particle hyperthermia. As prepared nanoparticles showed ferrimagnetic behavior at room temperature with magnetization of about 33.83 emu/g at +/- 15 kOe. The solid state MgFe2O4 nanoparticles exhibited specific absorption rate (SAR) of about 297 W/g at physiological safe range of frequency and amplitude. The increase in SAR and heating temperature in ac magnetic field was thought to be due to enhancement in magnetic hysteresis loss caused by dipole-dipole interactions in combustion synthesized MgFe2O4 nanoparticles.
