摘要

The diluted magnetic semiconductor, Zn0.568Mn0.432Te, is studied by means of neutron diffraction and cold neutron scattering below 100 K. Distribution of magnetic diffuse scattering intensity indicates the coexistence of two kinds of antiferromagnetic short-range orders, i.e. type-III and type-I in a face centered cubic Mn sublattice. The type-I short-range order component decreases below spinglass transition temperature, Tg = 17 K, by applying a magnetic field of 5 Tesla. We newly found a marked increase of quasi-elastic scattering intensity at Tg and an unknown broad inelastic peak lying around 1.0 meV at 14 K.
