Abstract(in English) The magnetic properties and thermal stability of AFC media with thin Co interlayers are investigated. Since thermal stability is strongly dependent on the exchange coupling constant J_ in the AFC media, the thin Co interlayers were inserted on both interfaces of the Ru layer to obtain higher values of J_. The J_ above 0.6 erg/cm^2 was obtained in the AFC media with the Co interlayers above 1 nm in comparison with about 0.1 erg/cm^2 in the conventional AFC media without the Co interlayers. From micromagnetic simulation results, it was observed that the AFC media with the Co interlayers had higher thermal stability behavior than the AFC media without Co interlayer.
