摘要： A method of manufacturing a magnetoresistance element which can reproduce magnetic signals with higher sensitivity. The manufacturing method includes the steps of providing a vacuum below 10−9 Torr in a film forming chamber for forming a nonmagnetic layer and ferromagnetic layer; performing plasma-etching of the surface of a substrate body by using a mixture of a gas (a) containing at least oxygen or water introduced into the chamber and an Ar gas (b) introduced into the chamber in a vacuum, state controlled to higher than 10−9 Torr; and forming the nonmagnetic and ferromagnetic layers on the etched substrate body by sputtering a prescribed target by using the mixture of the gases (a) and (b).

摘要： An MR element in a CPP structure includes a spacer layer made of Cu, a magnetic pinned layer containing CoFe and a free layer containing CoFe that are laminated to sandwich the spacer layer. The free layer is located below the magnetic pinned layer. The free layer is oriented in a (001) crystal plane, the spacer layer is formed and oriented in a (001) crystal plane on the (001) crystal plane of the free layer. Therefore, in a low resistance area where an area resistivity (AR) of the MR element is, for example, lower than 0.3 Ω·μm2, an MR element that has a large variation of a resistance is obtained.
