Abstract

We have explored a new electrically conductive underlayer material to grow (001) textured L1₀-FePt films on glass substrates for potential application in ultrahigh density magnetic recording media. We found (Mg _0.2Ti_0.8)O (MTO) polycrystalline film grows with a strong (001) texture on Cr buffer layer, which induces strong (001) texture of L1 ₀-FePt polycrystalline and granular films. Strong perpendicular anisotropy of 3.8 × 10⁷ erg/cm³ and coercivity of 15 kOe of a FePt-C film has been demonstrated using the MTO underlayer on glass substrates.
