We analyzed microstructures of current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) devices with Co-based Heusler alloy by a transmission electron microscope. Based on the relationship between the microstructure and transport properties, we conclude that the structural and electrical matching between the spacer material and ferromagnetic electrode are important for the high GMR.
