Nonlinear Temperature Characteristics in Magnetic Nanoparticles Due to Alternating Magnetic Field-Induced Hysteresis Heat
This paper investigates the different forms of temperature rise with time due to the nonlinear thermal characteristics in the magnetic nanoparticle (MNP) subjected to an external alternating magnetic field. The magnetic hysteresis-generated heat dissipation leads to the nonlinear thermal characteristics in the MNPs. The nonlinear characteristics results in the different forms of temperature rise with time for the same initial conditions. Different forms of temperature rise with time were found in past experiments. These forms include that temperature is proportional to time, square root of time, exponent of time, etc. This study reveals the various relations of temperature with time in the MNPs subjected to an external alternating magnetic field for the same initial condition.
