| 英文摘要 | The compound PrBa₂Cu₄O₈ were prepared under ambient oxygen pressure. Its structure of PrBa₂Cu₄O₈ has been refined from X-ray powder diffraction data by the Rietveld method. The major phase of the product were confirmed to be PrBa₂Cu₄O₈, with four minor impurity phases confirmed. The multiphase refinement process determines weight fractions of all the phases. Refined cell parameters of PrBa₂Cu₄O₈ in the orthorhombic space group Ammm, are: a=3.8901(1)Å, b=3.9041(2)Å, and c=27.3219(1)Å. Characterization of this compound by electrical resistivity and magnetization are also reported. |
