Nanostructured silicon (N-Si) was prepared by anodic electroetching of p-type silicon wafers. The obtained magnetic particles were separated by a permanent neodymium magnet as a magnetic nanostructured silicon (mN-Si). The N-Si and mN-Si exhibited different magnetic properties: the N-Si exhibited ferromagnetic-like behaviour, whereas the mN-Si exhibited superparamagnetic-like behaviour.

永久性钕磁铁收集的纳米结构硅铁磁铁

纳米结构化的硅（N-Si）是通过对p型硅片进行阳极电蚀刻而制备的。所获得的磁性颗粒由作为磁性纳米结构硅（mN-Si）的永久钕磁铁分离。N-Si和mN-Si表现出不同的磁性：N-Si表现出类似铁磁的行为，而mN-Si表现出超顺磁性的行为。
