Abstract

Excited levels of isolated nearest‐neighbor Mn‐Mn pairs of Zn_1−xMn_xS, Zn_1−xMn_xSe, and Zn_1−xMn_xTe 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 2J_NN are −2.78, −2.12, and −1.64 meV for the three studied systems, respectively.
