magnetic iron

基本解释

The physical core is crystallized in magnetic iron-nickel alloy-composite. The core is not hollow.
物质核心是磁性铁镍合金复合材料的结晶，其核心不是中空的。

As a magnetic iron cobalt tip moves close to the sample, the atoms’ nuclear spins become attracted to it and generate a small force on the cantilever.
随着一个磁性钴铁针靠近样本，样本的原子核磁旋开始被其吸引并且对硅悬臂也产生一个作用力。
Grünberg's team created a sandwich of two several-atom-thick layers of magnetic iron separated by a layer of nonmagnetic chromium between them.
Grünberg的团队创造了由两片几个原子厚的磁性铁，之间隔着一层无磁性的铬层的三明治。

The researchers first created separate nanoparticles of two materials, lead selenide and magnetic iron oxide, with precise dimensions.

Even so, he pointed out that some nanoparticles potentially serving as the basis for savvy devices of the future are already in use, including magnetic iron oxide particles used for advanced body imaging.

That would change the way the magnetic field of the iron oxide interacts with the semiconducting behaviour of the lead selenide.
