摘要：
CoCr and CoCrPt thin films on Cr or CrTi underlayers were studied to improve the magnetic properties for permanent magnetic stabilization layer application in anistropic magnetoresistance/giant magnetoresistance devices. Their structural and magnetic properties were investigated as a function of Pt content in magnetic layer, Ar gas pressure, Cr underlayer thickness or Ti content of CrTi underlayer and post-deposited annealed temperature. High coercivity H-c values (2000 Oe) can be achieved even remanence-thickness product (Mr delta) less than 1 memu/cm(2) during room temperature deposited using proper magnetic alloy and deposition processes. Post-deposited annealed further improved the coercivity of the cobalt films up to 3500 Oe as Mr delta was reduced from 1.2 to 0.5 memu/cm(2) (c) 2004 Elsevier Ltd. All rights reserved.
