Abstract

In this paper, Fe3Si nanoparticles were fabricated and studied for alternating magnetic field heating. High-magnetic-moment and large magnetic anisotropy energy barrier were found for those particles through the temperature-dependent magnetic characterization and dynamic coercivity analysis. Although a large hysteresis area was expected for the nanoparticles to generate appreciable heat, it is not necessary so when only the criteria of saturation magnetization and magnetic anisotropy energy barrier are fulfilled. Heating performance of Fe3Si nanoparticles was investigated. Field-dependent magnetic characterization unravels the fact that sufficient switching of magnetic nanoparticles is critical for heat generation.
