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 TC∼9.5 K. Comparing with other CaAl2Si2-type diluted magnetic semiconductors, we will show that negative chemical pressure suppresses the Curie temperature.
