Presents a study which examined magnetic bubble collapse in the presence of a microwave field. Modification of the analysis of bubble domain wall motion; Manner in which the size of a normal static bubble domain was determined in the Thiele² theory; Result that occurs if the region at and near the bubble is excited by a microwave field.

Presents an observation of the process of magnetic bubble generation by microwave excitation. Details on the experimental arrangement; Power required for bubble generation under fixed bias, frequency, and pulse width conditions; Observation of the real time process of bubble nucleation and growth for short pulse widths.
