Abstract

Coupling between electronic spins in rare earth doped TeN and BiN clusters is investigated by size selective Stern—Gerlach deflection experiments. The results are interpreted in terms of Dy3+(Te N )3− and Dy3+(Bi N )3− structures. This magnetochemical approach is consistent with a Zener type exchange spin coupling between valence electrons and the localized electrons in the impurity core.
