Abstract
A method is described for determining the magnetization and intrinsic length of thin magnetic films which support magnetic bubble domains. It is shown that from a calculation of the energy of the stripe domain configuration and Thiele's curves for circular domain collapse conditions, the magnetization and intrinsic length may be determined from the measurements of the film thickness, the domain period, and the bubble collapse field.
