Abstract

The fundamental method of aligning unoriented magnetic moments is to apply a magnetic field in the desired direction of orientation. The moments in "soft" magnetic materials, such as the coatings of recording media (e.g., iron oxide and chromium dioxide particles in plastic binders), tend to remain in the new orientation when the field is removed.
