| Abstract: | The evolution of a magnetic domain structure induced by temperature and magnetic field is reported in silicondoped yttrium iron garnet(YIG) films with perpendicular anisotropy.During a cooling-down procedure from300 K to 7K,a 20%change in the domain width is observed,with the long tails of the stripes being shortened and the twisting stripes being straightened.Under the influence of the stray field of a barium ferrite,the garnet presents an interesting domain structure,which shows an appearance of branching protrusions.The intrinsic mechanisms in these two processes are also discussed. |
