| Popis: | The process of domain structure formation and evolution after magnetization of a small area of a garnet ferrite film to saturation was examined with the use of modified two-step high-speed photography. It was found that the radial deformation caused by magnetizing coil breaks the uniaxial anisotropy of the specimen and results in formation of the axially oriented stripe domain structure inside the magnetization reversal area. The period of this domain structure decreases with the increasing amplitude of the pulsed field. The formation of the axially oriented stripe domain structure occurs under the axially symmetrical magnetostatic field. |
