摘要
We have completed a systematic investigation of the structural and magnetic properties of CaB6 over a wide range of temperatures. Unlike conventional magnetic systems, the mechanism for magnetism in this compound appears to be intimately connected to defects. We present direct evidence that introducing defects not only enhances the magnetization but also increases the ordering temperature.
