anisotropy among these Fe-N films is small. The saturation magnetizations of Fe-N films vary with increasing film thickness from 23.5 to 85.1 A?m2/kg. Key words: Fe-N thin film; coercivity; magnetic... are expected to have several advantages over crystalline Fe-N films such as lower magnetic anisotropy because of the isotropic nature of the amorphous structure[13-14]. Some reports have been given......

; 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......

Therefore, coils attached to the winding... system with magnetic flux, including the trackability and decoupling ability, are checked. However, the signal acquisition of the magnetic flux is not considered. The induction method is effective......
Magnetic Properties of Nd12Co6Pb Compound () Abstract:The magnetic and magnetocaloric properties for the Nd12Co6Pb compound were investigated. The Curie temperature TC of the magnetic transition of Nd12Co6Pb compound is 194 K. The experimentally determined magnetic effective paramagnetic moment is μeff=12.36 μB per formula unit (3.49 μB per Nd atom). The maximum magnetic entropy change......
