摘要: The deterministic Landau-Lifshitz-Gilbert equation has been used to investigate the nonlinear dynamics of magnetization and specific loss power in magnetic nanoparticles with uniaxial anisotropy driven by a rotating field. We propose new type applied field, which is "simultaneously alternating," i.e., direction external field changes periodically. show that more efficient heat generation possible this we suggest its experimental realization cancer therapy requires enhancement energies.
