摘要：

Structural and magnetic properties have been studied for polycrystalline Zn1-xTMxO, where TM (transition metal ions) = Mn, Fe and Co. Phase pure samples demonstrate Curie-Weiss behavior with antiferromagnetic interactions. Different synthesis conditions lead to formation of impurities that are responsible for spin-glass behavior (ZnMnO3 impurity in Zn1-xMnxO) or high-temperature ferromagnetic ordering (Co metal in Zn1-xCoxO or (Zn,Fe)(3)O-4 in Zn1-xFexO). No bulk ferromagnetism was observed for single-phase materials, contrary to the existing theories. (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA. Weinheim.
