  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.

  The tetrameric Cu(β-diketonate) alkoxide complex [Cu(thd)(OCH2CH2OCH3)]4 (thd = 2,2,6,6-tetramethyl-3,5-heptanedionate; 1a) reacts with the alkaline earth metal alkoxides [M(OCH2CH2OCH3)2] (M = Ca, 2a; M = Sr, 2b; M = Ba, 2c) to yield the heteronuclear compounds [Cu2M(thd)3(OCH2CH2OCH3)3] (M = Ca, 6a; M = Sr, 6b). These heterometallic complexes were also obtained in the reaction of 1a and the mixed

  Organometallic-derived ceramic compositions surrounding YBa2Cu3O7–x (123) were evaluated via DTA-TG runs and dilatometric densification. The compositions were either Y, Ba or Cu deficient respect to 123. For the Yttrium deficient compact the presence of liquids containing 0–1.3 mole %YO1.5—capable of dissolving the 123 grains—can promote a rapid sintering behavior. For Copper deficient compact the main densification/contraction mechanisms were delayed till 985 °C. For both Barium and Copper deficient compacts a strong exudation of liquids was detected at 990 °C and 1020 °C, respectively.

  通过 DTA-TG 运行和膨胀致密化评估了 YBa2Cu3O7-x (123) 周围的有机金属陶瓷成分。成分对于 123 来说是缺乏 Y、Ba 或 Cu 的。对于缺乏钇的压块，含有 0-1.3 摩尔%YO1.5 的液体（能够溶解 123 颗粒）的存在可以促进快速烧结行为。对于缺铜压块，主要的致密化/收缩机制被延迟到 985 °C。对于缺钡和缺铜的压块，分别在 990 °C 和 1020 °C 时检测到强烈的液体渗出。

  Abstract Ba(Mg1/3Ta2/3)O3 [BMT] dielectric ceramics are prepared by solid state (one step, two step and molten salt synthesis) and wet chemical methods (precipitation, citrate gel and sol–gel). The formation mechanism of BMT in each synthesis technique is discussed. The formation temperature and particle size of the formed BMT were found to be much lesser (in nanometer range) for solution synthesized

  摘要 Ba(Mg1/3Ta2/3)O3 [BMT]介电陶瓷采用固态（一步法、两步法和熔盐合成）和湿化学法（沉淀法、柠檬酸凝胶法和溶胶-凝胶法）制备。讨论了每种合成技术中BMT的形成机制。发现对于溶液合成粉末，形成的 BMT 的形成温度和粒度要小得多（在纳米范围内）。发现通过溶胶-凝胶法合成导致在约 600 °C 下形成超纯 BMT 纳米粉末，平均晶粒尺寸约为 18 nm，而在固态合成中，BMT 的形成是在约 1100 °C 下形成的平均晶粒尺寸为 220 nm。在烧结这些粉末时，发现化学衍生粉末的致密化和晶粒生长低于固态合成的 BMT 粉末。这导致溶液合成 BMT 样品的密度和微波介电特性略有下降。发现微波介电性能随着烧结BMT陶瓷平均粒径的增加而提高。

  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

  We have investigated the interaction of Pt with single-crystal SrTiO3(001) and polycrystalline Ba0.7Sr0.3TiO3 thin films using photoemission spectroscopies. Significant band bending is caused by interface formation, determining the Schottky barrier height. We have depth profiled the band bending for Ba0.7Sr0.3TiO3 thin films, giving a direct measurement of the depletion depth and built-in potential
