In this study, Bentonite/Fe3O4 nanocomposites were synthesized by the combination of magnetic nanoparticles and bentonite in the presence of an external magnetic field (PEM) and the absence of an external magnetic field (AEM). Synthesis nanocomposites were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), thermogravimetric analysis (TGA), and Fourier-transform infrared (FTIR). The saturation magnetization (M-S) of the bentonite/Fe3O4 nanocomposite was increased from 23 emu/g for the samples synthesized in the AEM to 58 emu/g for the samples synthesized in the PEM. By applying a magnetic field during the synthesis process, the value of specific loss power (SLP) of the nanocomposites has been increased about 100% in comparison with the synthesized sample in the AEM. This method can be used to obtain a higher SLP value which is favorable in hyperthermia application for cancer therapy.
