Abstract: Off-axis electron holography was used to observe and quantify the magneticmicrostructure of a perpendicular magnetic anisotropic PMA recording media.Thin foils of PMA materials exhibit an interesting up and down domainconfiguration. These domains are found to be very stable and were observed atthe same time with their stray field, closing magnetic flux in the vacuum. Themagnetic moment can thus be determined locally in a volume as small as few tensof cubic nanometers.
