在高浓度锰的黄铜矿晶体ZnGeP2：Mn中观察到锰团簇的磁共振信号异常强烈的分散。检测到的EPR信号对应于两种类型的孤立的锰离子。其中之一显然具有受主性质，这使得锰成为一种自含杂质，根据最近的理论预测，它可以形成铁磁态。
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.
