| 中文摘要 | High quality LaOFeP superconducting materials have been successfully synthesized by a two- step solid reaction method. We first prepared a La - Fe - P ternary alloy following a pre- alloying treatment; the resultant La - Fe - P ternary alloy was found to be the key precursor for producing the final LaOFeP superconductors in our experiments. The LaOFeP samples in general have a superconducting transition temperature of about T-c approximate to 4.1 K as demonstrated by the measurements of resistivity and magnetic susceptibility. The volume ratio of the superconducting phase in the high quality sample is estimated to be as high as 95% at the temperature of 2 K. Structural analysis by means of x- ray diffraction, electron diffraction and high resolution transmission electron microscopy shows that the LaOFeP crystal has a layered tetragonal structure with a P4/nmm space group. Structural defects such as stacking faults in the LaOFeP sample have also been briefly discussed. |
