Abstract
The domain wall dynamics in thermomagnetic recording of TbFeCo amorphous films is interpreted in terms of a model comprising magnetization reversal nucleation followed by a wall displacement process. The nucleation of the reversed domain from the saturated magnetization state occurs with a field usually observed as a nominal coercivity in Kerr or magnetization hysteresis loops. The concept of wall coercivity, which is often smaller than the nucleation field, is explicitly incorporated in the stability condition of the cylindrical domain during the wall displacement process. The model predicts both the recorded domain size and its dependence on recording power and applied field.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
