Modeling of Thermally Assisted Magnetodynamics

Banas L, Prohl A, Slodička M. Modeling of Thermally Assisted Magnetodynamics. SIAM Journal on Numerical Analysis. 2009;47(1):551-574.Thermomagnetic recording uses local heating of ferromagnetic media to locally decrease coercivity and change saturation magnetization of the material and alleviate magnetization reversal. A modified Landau–Lifshitz equation is proposed as a phenomenological model to allow for changes in magnetization magnitude and is studied both analytically and numerically
