Beschreibung
Zusammenfassung:	A manufacturing method of a magneto-resistive effect device, the manufacturing method includes steps of: forming an Mg film on a substrate on which a reference layer is formed and oxidizing the Mg film to form an MgO layer on the reference layer; heating the substrate on which the MgO layer is formed; after the step of heating, forming an Mg layer on the MgO layer; cooling the substrate on which the Mg layer is formed; and forming a free layer on the Mg layer in a state where the substrate is cooled by the cooling step, and the step of forming the Mg layer, the step of cooling, and the step of forming the free layer are performed in the process same process chamber.
