摘　　要：用自助熔剂法生长了ＰｒＢａ２Ｃｕ３Ｏ７－δ单晶．用一种简易的退火方法获得了无（１１０）孪晶的ＰｒＢａ２Ｃｕ３Ｏ７－δ晶体．用金相显微术、Ｘ－射线能谱以及Ｘ－射线衍射对生长单晶和退火单晶分别进行了表征，测量并讨论了ａｂ面内的各向异性电阻．PrBa 2CuO 7-δ single crystals have been grown using a self-flux method. Untwinned PrBa 2CuO 7-δ Crystals were obtained using a simple annealing approach. The as-grown and annealed crystals have been characterized by the optical microscopy, x-ray energy dispersive spectra, and x-ray diffraction. We have also measured and discussed the anisotropic resistivity within ab plane.
