Transport methods using high speed photography and ferromagnetic resonance are compared for the determination of the dynamic characteristics of bubble materials. The mobility and the saturation velocity are calculated with the use of parallel and perpendicular magnetic resonance fields and linewidth. Experiments are performed with 2‐&mgr;m bubbles Ga, Al or (Ca, Ge) substituted (Eu, Lu)3Fe5O12and (Y Sm Lu Ca)3(Fe Ge)5O12garnet films. In films experimented with, the mobilities range between 400 and 1000 cm/S Oe and the saturation velocities between 800 and 2000 cm/s. A good agreement has been found between both methods.
