Structure and magnetism in ultrathin iron oxides characterized by low energy electron microscopy

Benito Santos, Elena Loginova, Arantzazu Mascaraque, Andreas K Schmid, Kevin F McCarty, Juan de la Figuera

摘要:

我们已经在钌上生长了几个原子层厚的氧化铁外延膜。我们用低能电子显微镜表征生长。使用选区衍射和强度与电压谱,我们检测到两个不同的阶段,这是分配给浮氏体和磁铁矿。自旋极化低能电子显微镜显示磁畴图案的磁铁矿相在室温下。

英文摘要:

We have grown epitaxial films a few atomic layers thick of iron oxides on ruthenium. We characterize the growth by low energy electron microscopy. Using selected area diffraction and intensity vs. voltage spectroscopy, we detect two distinct phases which are assigned to wustite and magnetite. Spin polarized low energy electron microscopy shows magnetic domain patterns in the magnetite phase at room temperature.
