Laser annealing can permanently alter the magnetic properties of Ga-substituted magnetic bubble epitaxial garnet films. Laser annealing such films causes their saturation magnetization (4 pi M(s)) to increase as a function of the applied laser power. This is evidenced in annealed films by a decrease in domain periodicity, and increase in bubble collapse field and changes in the ferromagnetic resonance (FMR) spectra.
