Specific heat, magnetic susceptibility, and the spin-glass transition inHg1−xMnxSe

Abstract

The specific heat of the two mercury compounds ${\mathrm{Hg}}_{1-x}{\mathrm{Mn}}_x\mathrm{Te}$ and ${\mathrm{Hg}}_{1-x}{\mathrm{Mn}}_x\mathrm{Se}$ is almost identical. The phase diagram for ${\mathrm{Hg}}_{1-x}{\mathrm{Mn}}_x\mathrm{Se}$ is more complete and is different from that of ${\mathrm{Hg}}_{1-x}{\mathrm{Mn}}_x\mathrm{Te}$. The specific-heat data for low Mn concentration are still not understood.
