“…The specific absorption rate (SAR) is a parameter that characterizes the heating power of a substance at the fixed values of intensity and frequency of the alternating magnetic field. The SAR value varies widely for different materials from 0.35 to 6000 W/g. , The most promising materials that can be used in designing the practice are nanoparticles of ferrite, , manganite, , and gadolinium-based alloys. , Heating of ferromagnetic particles occurs due to two mechanisms: the Néel relaxation of magnetization (hysteresis process) and the mechanical rotation of the particles. Consequently, the magnetic properties of particles, their size, architecture, and viscosity of the medium are the key parameters determining the SAR value.…”
