Amorphous Magnetic Film Patterned Media with Columnar Structure
2009
Journal of the Magnetics Society of Japan
Preserved Fulltext
Magnetic properties of amorphous TbFeCo magnetic film on periodic nanodot pattern were examined. Cross sectional TEM image revealed the magnetic film deposited on a nanodot pattern with two dimensional periodicity of around 28 nm had columnar structure on the convexity portion. Measured magnetic properties and magnetic force microscope images indicated miniaturization of the magnetic domain attributed to the reduction of magnetic exchange coupling between the columns.
