Latest Patents
One of Sano's latest patents is a GMR device having an improved free layer. This invention addresses the challenge of negative magnetostriction in structures that include copper laminates within CoFe or CoFe/NiFe composites. By applying an oxygen exposure treatment to the copper laminates, Sano has achieved a low positive magnetostriction constant, which can be further adjusted by varying the thickness of the free layer and the configuration of the copper laminates.
Another notable patent is the development of a FeTa nano-oxide layer as a capping layer for enhancing giant magnetoresistance in bottom spin valve structures. This invention features an NiCr seed layer-based bottom spin valve sensor element that incorporates a synthetic antiferromagnet pinned layer and a capping layer made of either a single nano-oxide layer or a bi-layer structure. The resulting elements demonstrate higher GMR ratios and lower resistances compared to previous designs.
