摘要

通过在母体化合物中掺杂Na和Mn，成功合成了一种新型稀释磁性半导体(Sr, Na)(Zn, Mn)2Sb2，其晶体结构(空间群，164号)与122型铁基超导体具有相同的结构。当仅自旋掺杂(Zn, Mn)取代时，未观察到磁有序。只有在载流子共掺杂(Sr, Na)取代时，在最高居里温度~ 9.5 K以下才会出现铁磁有序。与其他类型的稀释磁性半导体相比，我们将证明负化学压力抑制居里温度。

A -Type Magnetic Semiconductor (Sr, Na)(Zn, Mn)2Sb2 Isostructural to 122-Type Iron-Based Superconductors
A new diluted magnetic semiconductor (Sr, Na)(Zn, Mn)2Sb2 has been successfully synthesized by doping Na and Mn into the parent compound , which has a -type crystal structure (space group , No. 164, ) isostructural to the 122-type iron-based superconductor . No magnetic ordering has been observed when only spins are doped by (Zn, Mn) substitution. Only with carriers codoped by (Sr, Na) substitution, a ferromagnetic ordering occurs below the maximum Curie temperature ∼9.5 K. Comparing with other -type diluted magnetic semiconductors, we will show that negative chemical pressure suppresses the Curie temperature.
