With the goal of achieving low frequency and low dose agents in therapeutic applications, it is discovered that γ-Fe2O3 can attain hyperthermia temperature at minimum concentrations of 5 mg/ml and at 200 kHz. Magnetic anisotropy of γ-Fe2O3 sample represents that Brownian relaxation i.e., rheological mode of relaxation is dominating over Néel or magnetic relaxation. Presence of 2BOP introduces an effective method for improving heating efficiency by increasing the colloidal stability of magnetic nanoparticles, as it is critical to immobilise these nanoparticles in an aqueous suspension. Presence of dipolar interaction causes the agglomeration of nanoparticles but inclusion of a non-magnetic system allows the adjustment of the mean separation between magnetic nanoparticles, which can reduce this dipolar interaction coupling to stabilise the nanoparticles and prevent further aggregation.
