Heating Loss Mechanism in β-NaFeO 2 Nanoparticles for Cancer Treatment Under Alternating Field
The induction heating loss mechanism in nanofluids prepared using synthesized β-NaFeO2 nanoparticles have been discussed with respect to optimization of magnetic relaxation (Neel and Brownian) losses, specific absorption rate (SAR), intrinsic loss power (ILP)as well as concentration of nanoparticles. The highest value of SAR for β-NaFeO2 nanoparticles has been found to be 282.3 W/g at 335.2 Oe field and 267 kHz frequency.The value of Brownian and total relaxation time has been calculated theoretically and found to be τΒ= 6.126x10-4 sand τ= 2.668x10
