Fabrication and magnetic properties of CoPt perpendicular patterned media

CoPt dot-arrays with dot diameters ranging 80–1000 nm have been fabricated by using electron beam lithography and reactive ion etching. The fabricated dots had their magnetic easy axes perpendicular to the plane. Dots with 80-nm-diameter were observed as single domain by magnetic force microscopy. T...

Description
Summary:CoPt dot-arrays with dot diameters ranging 80–1000 nm have been fabricated by using electron beam lithography and reactive ion etching. The fabricated dots had their magnetic easy axes perpendicular to the plane. Dots with 80-nm-diameter were observed as single domain by magnetic force microscopy. The CoPt dot-array with 80-nm-diameter showed much higher thermal stability than continuous films.
