Atomistic simulation of magnetic nanoparticles to investigate its effect in alternating magnetic field
Source abstract
Abstract
Magnetic nanoparticles have recently gained immense significance in medical research. From the standpoint of application in medical science NPs, the effect of temperature and NPs size on magnetic properties needed to be better understood. This work focused on a promising candidate, i.e., ferromagnetic Co@Fe core–shell NPs. The magnetization processes of perfect single-domain particles were computationally simulated to assess the effectiveness of a limited alternating magnetic field (AMF) and was observed that the effectiveness is higher for NPs with larger diameters (i.e., 20 nm). The Co@Fe nanoparticles (NPs) with different fractional radii were also simulated. At room temperature, the maximum heating power of 1.55 MJ/s was obtained for 0.8Co@1.0Fe (20 nm) with an AMF of 1.2 MHz.
