| Popis: | Anomalously intense dispersion was observed in the magnetic resonance signals of manganese clusters in the chalcopyrite crystal ZnGeP2:Mn with a high concentration of manganese. The EPR signals detected corresponded to two types of isolated manganese ions. One of these apparently possesses acceptor properties, which makes manganese a self-contained impurity for the formation of a ferromagnetic state in accordance with recent theoretical predictions. |
