According to the results of electron diffraction reported in the literature this carbon allotrope has a space group Fm \(\bar{3}\) m (group number 225) with a lattice parameter of about 3.54–3.57 Å. Nevertheless, because of the closeness of its lattice parameter to that of diamond...
中文: X射线的实验结果表明:样品均形成了在a-b方向上具有双倍周期的钙钛矿结构,属于立方晶系,晶体空间群为Fm3m(No225). Sr2YRuO6原胞为立方结构(a=0.8164nm),Y离子和Ru离子分别有序占据4a(0,0,0)和4b(1/2,1/2,1/2)原子等效位置.英文: Usually, cubic splines are expressed by four polynomial ...
Thecomposition was determined as Hg2Re0.5Ba4Ca1.5O8.5 and an univocal interpretation was found in terms of the high-symmetry space groupFm3m(225), with Z=2, (= 6.70 g/cm3; the reliability factor was 5.0%. This phase, Cu-free and not superconductive, rather than aprecursor can be ...
