| 中文摘要 | The exchange bias and thermal properties of Pt1-xMnx-Cr/NiFe films were investigated. Adding Cr into Pt1-xMnx film by inserting thin Cr layers was found to decrease the exchange bias considerably for x>0.5 but lead to a great enhancement of the pinning field along with unvarying coercivity and better thermal stability for xless than or equal to0.5. An optimum pinning field of similar to180 Oe was obtained for Pt0.55Mn0.45-Cr(4%) pinning 150 A NiFe-almost twice that of pure Pt0.55Mn0.45, and even larger than that of Pt0.5Mn0.5, by 20%. Although possessing a smaller grain size, Pt0.55Mn0.45-Cr(4%) has a higher blocking temperature than either pure Pt0.55Mn0.45 or Pt0.5Mn0.5. Structure characterization revealed that adding Cr promoted the ordering process of Pt1-xMnx (xless than or equal to0.5) greatly, and a perfect ordering phase of Pt(MnCr) was formed. The present results suggest that PtMn-Cr has favorable properties as a pinning layer. (C) 2004 American Institute of Physics. |
