Essay

Properties of magnetic characteristics crystals are stipulated by clusters of different type and size where indirect change interaction of antiferromagnetic character takes place among the atoms of 3d-elements through the atoms of halcogen. After studying optic and kinetic properties we have found the dominating mechanisms of dispersion.Fe atoms in Hg(1-x-у)Mn(х)Fe(y)S lead to the increase of thermoelectric quality coefficient (Z) in comparison with crystals Hg1-xMnхS which do not have Fe atoms and heat treatmet in sulphur vapours also results in the increase of Z. Zone parameters got on the basis of optic and kinetic studies allowed to build the chart of zone structure of the crystals under study.
