论文摘要
在这项工作中,我们使用预先选择的多型矩阵BI $ _ {0.9} $ gd $ _ {0.1} $ _ {0.1} $ _ {0.9} $ _ {0.9} $ mn $ _ {0.1} $ _ {0.1} $ $ $ o $ $ $ _ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $ _3 $(bgfmo),在这项工作中详细阐述和表征了纳米复合材料薄膜。这些纳米复合材料薄膜的局部铁电特征是通过压电响应力显微镜(PFM)研究的。通过局部操纵域探测了铁电域的切换行为。磁调查表明,在BGFMO基质中的过渡金属元素的掺入会在室温下引起宏观磁化的有趣增加。此外,研究薄膜的M(T)曲线中观察到自旋玻璃型行为。
In this work we elaborated and characterized nanocomposite thin films using a preselected multiferroic matrix Bi$_{0.9}$Gd$_{0.1}$Fe$_{0.9}$Mn$_{0.1}$O$_3$ (BGFMO) in the aim to enhance their basic ferroelectric and magnetic properties. The local ferroelectric character of these nanocomposites thin films was investigated by piezoresponse force microscopy (PFM). Switching behavior for ferroelectric domains was probed by locally manipulating domains. The magnetic investigation showed that the incorporation of transition metal elements in the BGFMO matrix brings out interesting increase in the macroscopic magnetisation at room temperature. Moreover, a spin glass type behavior is observed in M(T) curves for the studied thin films.
