The origin of thermal stability in laminated antiferromagnetically coupled media was investigated. A series of films were prepared to understand the role of top layer, bottom layer parameters and the antiferromagnetic coupling constant. Thermal stability factor (SF) was estimated from Sharrock's equation. SF showed an increase as a function of bottom layer thickness, indicating that the thermal stability depends on the thickness of bottom layer.
