【摘要】 用粉末X射线衍射法测定了三元化合物Fe₁1TiY的晶体结构。该化合物属四方晶系,其点阵常数为a=8.154×10^-10m。c=4.798×10^-10m。空间群为D（4h/17）-14/mmm.属ThMn₁₂结构类型。每个晶胞内含有2个化合式量,其中2个Y原子占据2（a）位置,22个Fe原子和2个Ti原子统计地占据8（f）,8（i）和8（j）位置,原子位置的分布参数为X_■=0.37,X■=0.27。更多还原

【Abstract】 The crystal structure of Fe₁1 TiY has been determined by means of X-ray powder diffraction. The unit cell is tetragonal with a=8.514 A and e=4.798 A at 25℃. There are two formula units per unit cell. The space group is D_4h¹⁷-I4/mmm. The two Y atoms occupy 2（a） positions, the two Ti atoms and twenty two Fe atoms occupy 8（f）, 8（i） and 8（j） positions with x_i=0.37 and x_i=0.27.更多还原
