- Abstract
- The influence of magnetic field amplitude on magnetization reversal kinetics and the magnetic hyperthermia effect produced by a single-domain ferromagnetic particle immobilized in a non-magnetic medium has been theoretically investigated. The calculation results, based on the mathematically regular Kramers theory, show that the dissipation W of alternating magnetic field energy in the particle can increase with field amplitude faster than according to the quadratic law W ∼ H20. This conclusion, at least in principle, explains recent experiments on magnetic hyperthermia in systems of immobilized particles, where the dependence was discovered W ∼Hγ0 , γ > 2.
