Abstract
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.
