Abstract
Coupling between electronic spins in rare earth doped Te-N and Bi-N cluster s is investigated by size selective Stern-Gerlach deflection experiments. T he results are interpreted in terms of Dy3+(Te-N)(3-) and Dy3+(Bi-N)(3-) st ructures. This magnetochemical approach is consistent with a Zener type exc hange spin coupling between valence electrons and the localized electrons i n the impurity core.
