We fabricated the composite perpendicular magnetic recording (PMR) media successfully for the first time by combining a nanogranular FeSiO soft layer and a [Co/PdSi]n hard layer. PdSi spacing layer (0–4 nm) was used to study the exchange coupling effects between the FeSiO(5 nm) and the [Co(0.26 nm)/Pd(1 nm)]14 layers in the composite films. Proper coupling occurs when PdSi interlayer is ∼0.5 nm. Significant lowering of the coercivity is observed for the composite PMR medium while still maintaining good thermal stability. The results prove the possibility to fabricate a writable PMR medium having an ultrahigh magnetic anisotropy constant Ku value.
