摘要
以Al2O3为衬底利用多能态离子注入法在离子注入设备上制备了一系列具有室温铁磁性的Al2O3∶Mn样品.在Al2O3的X射线衍射峰附近发现新的衍射峰,该衍射峰既可能对应一种未知新相,也可能对应Al2O3∶Mn固溶体.所有样品都具有磁滞现象和室温铁磁性.
Room-temperature ferromagnetic Al2O3： Mn samples are prepared with the multi-energy ion implantation method by an ion beam implantation system. A new diffraction peak is observed near the Al2O3, which corresponds to a new unknown phase or to the solid solution phase of AAl2O3： Mn. Magnetic hysteresis-loops of all Al2O3： Mn samples are obtained at room temperature. This indicates that all samples are ferromagnetic at room-temperature.
