摘要：
The postannealing effects on magnetic properties and microstructure of CoCrPt/Ti perpendicular recording media were discussed. An increase in the negative nucleation field and a decrease in intergranular exchange coupling with annealing temperatures was found to be observed for the films with a CrMn overlayer. The analaysis showed a coervitity of ∼7600 Oe and a negative nucleation field of ∼2400 Oe for a film with a CrMn overlayer annealed at 450°C for 5 min.
