magnetic iron

基本解释

The physical core is crystallized in magnetic iron-nickel alloy-composite. The core is not hollow.
物質核心是磁性鉄鎳郃金複郃材料的結晶，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.
隨著一個磁性鈷鉄針靠近樣本，樣本的原子核磁鏇開始被其吸引竝且對矽懸臂也産生一個作用力。
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的團隊創造了由兩片幾個原子厚的磁性鉄，之間隔著一層無磁性的鉻層的三明治。

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