Perpendicular recording applications use a soft magnetic underlayer (SUL) in the media to enhance the writer field and control its angle. In this paper, a micromagnetic/FEM model (MagPar) was used to investigate the physics of the write process while a nonlinear magnetoelectrical model (Klaassen) helped identify the value of the damping constant under a… CONTINUE READING
