Abstract

We report experimental results on the growth of Hg 1 −x−y Cr x Mn y Se crystals and their magnetic susceptibility χ( T) in dependence on the crystal structure and composition. It was found that the crystals with the Mn composition y=0.01–0.08 exhibit the spin-glass transition temperature T g=100–110 K. An increase of y value leads to the saturation of the χ max and T g characteristics in the composition ranges of y>0.06 and y>0.02, respectively. This phenomenon is explained as a result of phase-separated magnetic behavior caused by the formation of HgCr 2Se 4 inclusions and textures.
