  摘要：

  The metal oxides MgO, BaO, Al2O3, SiO2, MgO-Al2O3, CaO-Al2O3, SrO-Al2O3, BaO-Al2O3 and MgO-SiO2 have been coated onto ribbons of the Fe-based amorphous alloy Metglas 2605S3A using a set-gel process. The effects of the surface coating on the magnetic properties of the alloy are investigated. The d.c. hysteresis loop for ribbons coated with MgO and MgO-Al2O3 is more square shaped than that for the uncoated ribbon. For ribbons coated with BaO, SrO-Al2O3 and BaO-Al2O3 it is more inclined than for the uncoated ribbon. Significant differences in the frequency dependence of the effective permeability are observed that depend on the nature of the coated oxides. The core loss is also affected by the coating. These results may be explained in terms of a stress induced by the coating and the modification of the domain structure via elastic and/or magnetoelastic interactions. It is thought from the magnetoelastic interactions that the MgO and MgO-Al2O3 coatings induce tensile stresses whilst those of BaO, SrO-Al2O3 and BaO-Al2O3 induce compressive stresses.

• Alkali metal-containing, organometallic products

  An alkali metal-containing, organometallic product, which is hydrocarbon-soluble, is prepared by reacting an organo-alkali metal reactant in which the alkali metal atom is bonded to a carbon atom, e.g. cyclohexyl-lithium, with a di(organooxy)-alkaline earth metal reactant, e.g. di-n-butoxy-magnesium, in an organic solvent at about -20.degree. to +120.degree.C. The organo-alkali metal reactant can be prepared by reacting an organo halide with an alkali metal, and this can be done in situ, i.e. in the presence of the di(organooxy)-alkaline earth metal reactant. The organometallic product has approximately the same chemical reactivity as the organo-alkali metal reactant from which it is prepared, but is more soluble in hydrocarbon solvents.

  含有碱金属的有机金属产物，可溶于碳氢化合物，是通过将含有碱金属的有机金属试剂（其中碱金属原子与碳原子结合，例如环己基锂）与二(有机氧基)碱土金属试剂（例如二正丁氧基镁）在有机溶剂中在约-20度至+120度C反应制备而成。有机碱金属试剂可以通过有机卤化物与碱金属反应制备，这可以原位完成，即在二(有机氧基)碱土金属试剂存在的情况下进行。有机金属产物与其制备的有机碱金属试剂具有大致相同的化学反应性，但在碳氢化合物溶剂中更易溶解。

  Phase pure Ba(Mg13Ta23O3 (BMT) powders were prepared using Ba metal, Mg(OC2H5)2, and Ta(OC2H5)5 as metal-organic precursors. Thin films of BMT were spin coated onto Pt-coated Si(100) substrates using the prepared solution and then fired at various temperatures. The X-ray diffraction patterns show that the films crystallize to a single disordered perovskite phase on Si (100) at ~600 °C. Scanning electron
