| 1 | INTERFACE REACTION IN MAGNETIC MULTILAYERS显示文摘Ta/NiO/NiFe/Ta multilayers were prepared by rf reactive and dc magnetron sputtering. The exchange coupling field (Hex) between NiO and NiFe reached 120Oe. The composition and chemical states at the interface region of NiO/NiFe were studied using the x-ray photoelectron spectroscopy (XPS) and peak decomposition technique. The results show that there are two thermodynamically favorable reactions at NiO/NiFe interface: NiO+Fe=Ni+FeO and 3NiO+2Fe = 3Ni+Fe2O3. The thickness of the chemical reaction as estimated by angle-resolved XPS was about 1-1.5nm. These interface reaction products are magnetic defects, and we believe that the Hex and the coercivity (Hc) of NiO/NiFe are affected by these defects. Moreover, the results also show that there is an 'intermixing layer' at the Ta/NiO (and NiO/Ta) interface due to a thermodynamically favorable reaction: 2Ta+5NiO=5Ni+ Ta2O5. This interface reaction has an effect on the exchange coupling as well. The thickness of the 'intermixing layer' as estimated by XPS depth-profiles was about 8-10nm. | G.H. Yu, M.H Li, F. W Zhu, X.F.

| 2 | A transmission electron microscopy study of microscopic causes for localized-corrosion morphology variations in the AA7055 Al alloy显示文摘By Using(scanning) transmission electron microscopy, localized-corrosion morphology variations of the AA7055 AlZn(Cu)Mg alloy with different thermal processes and their underlying microscopic causes were investigated systematically. Our study shows that the corrosion resistance of the nanoscale precipitates varies with their structure type and Cu-content. Just like the Al-matrix, the early-stage precipitates are corrosion resistant, as compared with the η_p/η-precipitates without high Cu-content. With a high Cucontent, however, the η-precipitates become most corrosion resistant among all phases involved. Hence,tailoring the precipitate microstructure and chemistry though thermal processes may change the overall corrosion morphology and improve corrosion resistance property of the alloy. | X.B.

| 5 | INFLUENCE OF THE NONMAGNETIC METAL SPACER ON THE MAGNETIC PROPERTIES AND MICROSTRUCTURE OF THE MULTILAYER FILMS显示文摘Ta / NiFe/ Bi (Ag, Cu)/ FeMn /Ta and Ta / NiFeI /FeMn / Bi(Ag, Cu)/ NiFeII / Ta films were prepared by magnetic sputtering. The texture and the dependences of the exchange-coupling field on the thickness of Bi, Ag, and Cu in Ta / NiFe/ Bi(Ag, Cu) /FeMn /Ta and Ta/ NiFeI / FeMn / Bi(Ag, Cu)/ NiFeII / Ta films were studied. XPS results indicate that the Bi atoms migrated into the FeMn layer during the deposition process and a FeMnBi alloy was probably formed or the Bi atoms existed as an impurity in the FeMn layer in Ta / NiFe / Bi(Ag, Cu)/ FeMn / Ta. Otherwise, in Ta / NiFeI / FeMn / Bi(Ag, Cu) / NiFeII / Ta films, Bi, Ag, and Cu atoms do not remain entirely at the interface of the FeMn / NiFeII film, but at least partly segregate to the surface of the NiFe film. | M.H.
