摘要:

采用机械合金化法制备了Ba-Fe-As-P前驱体,为Ba-(As,P)助熔剂法生长BaFe $_2$(As $_{1-x}$ P $_x$)$_2$单晶提供了必要的前驱体。通过机械合金化,Ba-(As,P)前驱体在室温下在1小时内成功形成,显著缩短了制备时间。采用机械合金化前驱体,生长出尺寸达5~ mm $\times$ 5~mm $\times$ 0.1~ mm的BaFe $_2$(As $_{1-x}$ P $_x$)$_2$单晶。

英文摘要:

Mechanical alloying method has been employed to prepare the Ba-Fe-As-P precursors, necessary for the Ba-(As,P) flux growth of the single crystalline BaFe$_2$(As$_{1-x}$P$_x$)$_2$. By alloying constituent elementals mechanically, the Ba-(As,P) precursors are successfully formed at the room temperature within one hour, significantly reducing preparation time. Using the mechanically alloyed precursors, we have grown single crystals of BaFe$_2$(As$_{1-x}$P$_x$)$_2$ with the sizes up to 5~mm $\times$ 5~mm $\times$ 0.1~mm.
