Fabrication of a single-crystal giant magnetoresistive device on a polycrystalline film: Technique may promote practical use of high-performance magnetoresistive devices comprising half-metallic heusler alloys

Engineers have succeeded in fabricating a giant magnetoresistive (GMR) device comprising single-crystal Heusler alloys on an practical silicon substrate. The team demonstrated for the first time that a single-crystal magnetoresistive device can be bonded onto the surface of a polycrystalline electrode using a wafer bonding technique.
