Abstract
We have grown Mn-doped $Bi_2Se_3$ and $Sb_2Se_3$ single crystals using the temperature gradient solidification method. We report on the structural and magnetic propertis of Mn-doped $Bi_2Se_3$ and $Sb_2Se_3$ compound semi-conductors. The lattice constants of several percent Mn-doped $Bi_2Se_3$ and $Sb_2Se_3$ were slightly smaller than those of the un-doped samples due to the smaller Mn atomic radius ($1.40 {\AA}$) than those of Bi ($1.60 {\AA}$) and Sb ($1.45 {\AA}$). Mn-doped $Bi_2Se_3$ and $Sb_2Se_3$ showed spin glass and paramagnetic properties, respectively.
