Resumo

We report the first results of neutron diffraction studies of magnetic ordering phenomena in a wurtzite-structured diluted magnetic (semimagnetic) semiconductor Zn0.45Mn0.55Te. At low temperatures the system exhibits a short-range antiferromagnetic ordering, closely related to the antiferromagnetic structure seen in the wurtzite form of β-MnS. This type of ordering indicates short-range and antiferromagnetic only interactions between the Mn spins, in agreement with present theories of exchange mechanism in DMS materials. Similarly as in cubic DMS systems, the magnetic correlation range in Zn0.45Mn0.55Te exhibits a pronounced anisotropy.
