Abstract

We report the observation of an unusual phase assembly behavior during the growth of hexagonal LuFeO(3) thin films which resulted in the formation of epitaxial Fe(3)O(4) nanolayers. The magnetite layers were up to 5 nm thick and grew under the conditions at which Fe(2)O(3) is thermodynamically stable. These Fe(3)O(4) nanolayers act as buffer layers promoting a highly epitaxial growth of the hexagonal LuFeO(3) thin film up to 150 nm thick. Using scanning transmission electron microscopy, we show that the interface between (001) LuFeO(3) and (111) Fe(3)O(4) can be reconstructed in two ways depending on the sequence in which these compounds grow on each other. We suggest the polarity of the interface is the reason behind the observed interface reconstruction and epitaxial stabilization of magnetite.

摘要

我们在六方 LuFeO(3) 薄膜的生长过程中观察到一种不寻常的相组装行为，导致了外延 Fe(3)O(4) 纳米层的形成。这些磁铁矿层的厚度可达 5nm，并在 Fe(2)O(3)热力学稳定的条件下生长。这些 Fe(3)O(4) 纳米层作为缓冲层，促进了高达 150nm 厚的六方 LuFeO(3) 薄膜的高度外延生长。使用扫描透射电子显微镜，我们表明（001）LuFeO(3) 和 (111)Fe(3)O(4) 之间的界面可以根据这些化合物相互生长的顺序以两种方式进行重构。我们认为界面的极性是观察到的界面重构和磁铁矿外延稳定的原因。
