| 摘 要： | 采用无氟金属有机物沉积方法(MOD)在单品基底SiTrO3(100)上制备GdBa2Cu3O7-x(GdBCO)薄膜.所用的无氟MOD方法制备GdBCO薄膜具有前驱溶液稳定、薄膜致密性好以及相比于TFA-MOD方法在热处理过程中无HF气体的产生等优点.经过一系列热处理工艺后,对薄膜进行X射线衍射(XRD)分析、扫描电镜(SEM)分析以及超导性能的测试.通过熔融外延生长,得到c轴织构良好、表面平整致密、临界超导转变温度为90 K的GdBCO薄膜,77K自场下的临界电流密度约为0.6 MA/cm2.

| Abstract: | GdBCO films have been synthesized on single crystal substrates of SiTrO3(100)by using a fluorite-free MOD method. We have recently developed a fluorine-free MOD synthesis with several important advantages including precursor solution stability, improved film density, and elimination of HF during processing. The phase composition, microstructures and the critical temperature of superconductivity (Tc) and the critical current density (Jc) of GdBCO films have been investigated by x-ray diffraction (XRD), scann... |
