本文报道大尺寸LnBa2Cu3O7-δ(Ln=Y,Eu,Gd,Dy,Ho,Er,Tm,Yb,Lu)单晶生长及其超导电性,并讨论了(001)自然晶面的X射线多级衍射、劳厄相、旋进相等单晶鉴定法。The growth of large single crystal LnBa2Cu3O7-δ and their superconductivity is reported in this paper. Identification methods for single crystals e.g., Laue pattern, precession pattern and the OOL multiple-order diffraction with X-ray, are discussed.
