论文摘要
文献中存在有关大量ND0：5BA0：5MNO3的电子和磁性行为的矛盾报告。在这项工作中，我们研究了由脉冲激光沉积生长的Nd0：5ba0：5mno3的薄膜。通过原位反射高能电子衍射，原子力显微镜，X射线反射率和X射线衍射，在逐层模式下外延生长的成功已得到证实。发现这些薄膜是侮辱性的，并在低温下表现出旋转玻璃行为。该研究提供了一个机会，可以通过异质工程进行半掺杂的锰矿物的电荷/轨道订购与铁磁学之间的竞争。
Contradictory reports about the electronic and magnetic behavior of bulk Nd0:5Ba0:5MnO3 with uniform disorder exist in the literature. In this work, we investigate the thin films of Nd0:5Ba0:5MnO3, grown by pulsed laser deposition. The success of epitaxial growth in a layer-by-layer mode and high quality of the films have been confirmed by in-situ reflection high energy electron diffraction, atomic force microscopy, X-ray reflectivity, and, X-ray diffraction. These films are found to be insulting and exhibit spin-glass behavior at low temperatures. The study offers an opportunity to tune the competition between charge/orbital ordering and ferromagnetism in half-doped manganites through heterostructure engineering.
