Abstract

The domain observation technique using fine magnetic particles as small as 10 nm is very effective in investigating the high density recording states of various kinds of magnetic and magneto-optic recording media. Theoretical calculations predict that suppression of thermal agitation of spins within each particle greatly improves the image quality of observed domain patterns. This prediction has been experimentally verified by varying the sample temperature during evolution of the domain patterns. As the sample temperature decreases, high density recording states can be visualized more clearly and definitely owing to the suppression of thermal agitation of the spins.
