Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method for producing a new generation of giant magnetoresistance (GMR) sensors and tunnel magnetoresistance (TMR) sensors. According to the invention, a thin-film fixing layer is produced for example, from a 5d transition metal (W Rd, Os, Ir, Pt) or from a 4d transition metal (Pd, Rh, Ru) having a high magnetocrystalline anisotropy. Said thin-film fixing layer fixes the direction of magnetization of the fixed layer (3d ferromagnetic transition metals). A moment filter can be constructed with which the effectiveness of GMR and TMR sensors can be increased.

Why it's free to use
- Filed September 19, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 19, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 19, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
