Abstract
Excited levels of isolated nearest-neighbor Mn-Mn pairs of Zn1−xMnxS, Zn1−xMnxSe, and Zn1−xMnxTe have been studied by inelastic neutron scattering. The measurements have been carried out on several single-crystal and polycrystalline samples with x≤0.05 at various temperatures. Values obtained for the exchange constants 2JNN are −2.78, −2.12, and −1.64 meV for the three studied systems, respectively.Keywords
