我们介绍了一种新的机制巡游铁磁性，这是基于一个简单的两带模型，并通过使用数值和分析方法，我们表明，周期性安德森模型包含这种机制。我们建议的机制，这并不假设原子内的洪德耦合，是存在于铁组和一些f电子化合物。
We introduce a novel mechanism for itinerant ferromagnetism, which is based on a simple two-band model, and, by using numerical and analytical methods, we show that the periodic Anderson model contains this mechanism. We propose that the mechanism, which does not assume an intra-atomic Hund's coupling, is present in both the iron group and some f electron compounds.
