Investigation of the effect of the melting point (Tm) of various single oxides on the columnar growth and generation of the nucleation site for CoPt granular media deposited at room temperature were conducted. When oxide with Tm from 1857 °C to 2410 °C is added to the granular media, thickness of the heteroepitaxial growth of the magnetic grains on the Ru underlayer (columnar structure) decreases from 13 to 5.5 nm. The employment of oxide with Tm of the range from 450 °C to 2410 °C to the granular media will lead to the reduction of grain size from 5.6 to 3.0 nm, due to the suppression of the lateral grain growth by the high Tm oxide.
