Abstract

Single crystals of the solid solutions CdGeAs2:Mn(x) and Cd0.964Zn0.036GeAs2:Mn(x) have been grown by the vertical Bridgman method. An X-ray diffraction study has demonstrated that Cd0.964Zn0.036GeAs2 (I), Cd0.964Zn0.036GeAs2:Mn (1.5 wt%) (II), and Cd0.964Zn0.036GeAs2:Mn (2.18 wt %) (III) retain the CdGeAs2 structure (tetragonal system, space group I \(\bar 4\)2d). The unit cell parameters of the solid solutions are as follows: a = b = 5.934(1) Å, c = 11.219(2) Å for I; a = b = 5.919(1) Å, c = 11.204(2) Å for II; and a = b = 5.918(1) Å, c = 11.208(2) Å for III. Many of Mn atoms in II and III occupy interstitial sites in the crystal lattice. Selected electrical and magnetic properties of single crystals of CdGeAs2:Mn(x) are discussed.
