    摘要:

    采用鎵自助熔劑的方法生長出了UFeGa5單晶,采用X射線衍射技術(shù)和Rietveld方法對UFeGa5晶體結(jié)構(gòu)進(jìn)行了研究。結(jié)果表明:生長出的UFeGa5單晶體結(jié)構(gòu)完整,結(jié)晶性好。UFeGa5具有HoCoGa5型四方結(jié)構(gòu),空間群為P4/mmm(No.123),其晶格常數(shù)為a= 0.42533(2) nm, c= 0.67298(3) nm,并得到了透射電鏡(TEM)實驗驗證

    Abstract:

    High-quality single crystals of UFeGa5 were grown by the Ga-flux method. The structure of UFeGa5 single crystal was studied by X-ray diffraction and Rietveld method. The results show that the structure of as-grown UFeGa5 single crystal is good and its crystallinity is well. The UFeGa5 has the HoCoGa5 type-structure with space group P4/mmm (No.123). The lattice constants are a=0.42533(2) nm and c=0.67298(3) nm. The crystal structure results are confirmed by transmission electron microscopy
