Stability of parallel stripe domains

The stability of a periodic array of parallel stripe domains in LPE garnet films is investigate both theoretically and experimentally. The vehicle used is the confined region of the bubble lattice device [1] which allows the initialization of straight parallel stripes as well as allowing a variation in the period of the stripe domains. The domains are analyzed wlth respect to the stable number of straight parallel stripes for a given bias field and to their stability with respect to sinusoidal distortions (buckling). The results show that a stable range of bias exists between the upper limit of stripe contraction and the lower limit of stripe buckling.
