论文摘要
磁性是一个非常相关的主题，可以渗透我们的日常生活。但是，磁性不断使我们从惊讶到惊喜，这似乎表明这是一种不太了解的现象。例如，我们发现块状无定形钯变为磁性。因此，自然应该问，有缺陷的钯能否发展出磁性？特别是，无定形的多孔钯会变得磁性吗？在这里，我们证明了该问题的答案是肯定的，这种有缺陷的PD拓扑是磁性的，具有磁性取决于样品孔隙度的量和结构的拓扑。显然，如果在多孔无定钯中存在磁性，则表明有可能开发轻质磁铁，当需要最大化的磁性/重量比时有用，非常适合空间和航空应用。
Magnetism is a very relevant subject that permeates our everyday lives. However, magnetism keeps taking us from surprise to surprise which seems to indicate that it is a phenomenon not well understood. For example, we found that bulk amorphous palladium becomes magnetic; so, naturally one should ask, could defective palladium develop magnetism? In particular, would amorphous porous palladium become magnetic? Here we show that the answer to that question is affirmative, this defective topology of Pd is magnetic, with a magnetism that depends on the amount of sample porosity and on the topology of their structures. Clearly, if magnetism exists in porous amorphous palladium, this indicates the possibility of developing light-weight magnets, useful when a maximized magnetism/weight ratio is demanded, well suited for space and aeronautical applications.
