Computer simulation to investigate absorption of energies of arrayed disk‐like nanoiron particles under magnetic fields

In this research, we focus on the studying of absorbed energies of materials under an external magnetic field frequency of 0.5 GHz. This wave corresponds to microwave irradiation. The absorbent materials were arrayed disk‐like iron particles with dimension on the nanometer scale and magnetic responses of the particles were simulated by solving the Landau–Lifshitz–Gilbert equation. The external fields were applied from various directions and energies of absorption of the system were calculated. The maximum absorbed energies were found when the field was 135° ± 30° along the X‐axis or the Y‐axis. The current simulation demonstrated that the direction of applied field results in different absorption energies of the system.
