; magnetic recording system; uniaxial magnetic anisotropy; magnetic field annealing; texture 1 Introduction With the increasing areal density in magnetic recording system, CoCrPtTaB, the currently main magnetic recording media, has got to the superparamagnetism limitation[1]. Because of its very large uniaxial magnetic anisotropy (Ku=7.0×107 erg/cm3)[2] and huge coercivity [3], chemically ordered......
Magnetic property and microstructure of SmCo magnetic recording films李宁,李帅,张恩,王立锦Department of Materials Physics,University of Science and Technology Beijing摘 要:Cr/SmCo/Cr thin films with Sm concentration of 37.7 at.% were deposited on glass substrates by magnetron sputtering. Measurement of magnetic properties showed that the SmCo film possessed good......
