Abstract :
In this study, we have found that Cu and Ag underlayers grow with the Volmer-Weber growth mode on MgO(OOl) substrates at relatively low temperature of around 400 degC. Using these island-like grown films as templates, we have successfully fabricated magnetically decoupled L10-FePt particulate films with the perpendicular anisotropy at 520 degC.
