Abstract
If a loaded Al2O3 sphere is passed over SmGa and LuTb garnet crystalline films, the domain pattern is modified. The width of the changed pattern is proportional to the diameter of the zone of contact between the sphere and the garnet. The pattern depends on load: a herring-bone type is found at low loads, a parallel pattern at high loads. After a magnetic field has disturbed the pattern, a narrow region of straight domains is left, which persists unless the material is heated above 1100°C. The patterns are independent of the sign of the magnetostriction constants.
