Single Crystal Growth and Magnetic Properties of Mn-doped Bi2Se3 and Sb2Se3
Journal of Magnetics, Volume 9, Number 4, 31 Dec 2004, Pages 125-127
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 semi-conductors. 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 (1.40Å) than those of Bi (1.60Å) and Sb (1.45Å). Mn-doped Bi2Se3 and Sb2Se3showed spin glass and paramagnetic properties, respectively.
