Abstract

We have grown Mn-doped Bi₂Se₃ and Sb₂Se₃ single crystals using the temperature gradient solidification method. We report on the structural and magnetic propertis of Mn-doped Bi₂Se₃ and Sb₂Se₃ compound semiconductors. The lattice constants of several percent Mn-doped Bi₂Se₃ and Sb₂Se₃ were slightly smaller than those of the un-doped samples due to the smaller Mn atomic radius (1.40 Å) than those of Bi (1.60 Å) and Sb (1.45 Å). Mn-doped Bi₂Se₃ and Sb₂Se₃ showed spin glass and paramagnetic properties, respectively.
