摘要:
A magnetoresistive effect element is produced by forming a first magnetic layer, a spacer layer including an insulating layer and a conductive layer which penetrates through the insulating layer and passes a current, on the first magnetic layer, and a second magnetic layer all of which or part of which is treated with ion, plasma or heat, on the formed spacer layer.
摘要:
A method is for manufacturing a magnetoresistance effect element having a magnetization fixed layer, a non-magnetic intermediate layer, and a magnetization free layer being sequentially stacked. The method includes: forming at least a part of a magnetic layer that is to become either one of the magnetization fixed layer and the magnetization free layer; forming a function layer including at least one of an oxide, a nitride, and a fluoride on the part of the magnetic layer; and removing a part of the function layer by exposing the function layer to either one of an ion beam and plasma irradiation.

摘要:
There is provided a method for manufacturing a magnetoresistive element having a magnetization pinned layer, a magnetization free layer, and a spacer layer including an insulating layer arranged between the magnetization pinned layer and the magnetization free layer and current paths passing through the insulating layer. The method includes, in producing the spacer layer, depositing a first non-magnetic metal layer forming the current paths, depositing a second metal layer to be converted into the insulating layer on the first non-magnetic metal layer, and performing two stages of oxidation treatments in which a partial pressure of an oxidizing gas in a first oxidation treatment is set to 1/10 or less of a partial pressure of an oxidizing gas in a second oxidation treatment, and the second metal layer being irradiated with an ion beam or a RF plasma of a rare gas in the first oxidation treatment.
