CRITICAL FIELDS AND CRITICAL ANGLES FOR PULSE PRECESSIONAL SWITCHINGS OF THIN MAGNETIC FILMS

摘要

This field can be construed as the "processional coercively" of the film. In other words, no precessional switching occurs if the magnitude of the pulse is below the critical value regardless of the pulse duration. The case where the pulse field is applied under some angle with respect to the hard axis is analytically more involved although it can be treated along the same conceptual lines. The mathematical difficulties that appear in this case can be surmounted by using the "Cartesian rule of signs."
