摘要
A new phase of Gd_(2-x)Na_xCuO_4 was synthesized by direct precipitation from the mixture of Gd_2O_3 and CuO in the molten KOH/NaOH/KNO_3 solution at temperature as low as 280℃. The resulting precipitate was characterized by using SEM, XRD, EDX, XPS and magnetic method. The XRD data indicate that the precipitated Gd_(2-x)Na_xCuO_4 is monoclinic with lattice parameters a=8.6816, b=3.7233. c=6.0796. a=γ=90', 0=108.75° and V=186. 13.
