反钙钛矿薄膜的制备是一项具有挑战性的工作，因为其相图复杂，在加工过程中容易分解，这阻碍了其基础研究和应用。本文报道了用化学溶液沉积法在几种不同的单晶衬底上制备反钙钛矿型CuNCo3(CNC)薄膜。结果表明，无论衬底取向如何，所制备的CNC膜都是c轴取向的，表明自组装后的薄膜具有c轴取向。对薄膜的微观结构和物理性能进行了研究，结果表明：所制备的复合金属氮化物薄膜是一种铁磁性居里温度高于650K的新型软磁体，为制备反钙钛矿型钴基薄膜提供了一条有效的途径，也为溶液法研究复合金属氮化物薄膜的生长机理提供了一个原型。
Preparation of antiperovskite thin films is challenging work due to their complex phase diagram and easy decomposition during processing, which hinder the fundamental studies and applications. Herein, we report the preparation of antiperovskite CuNCo3 (CNC) thin films on several different single crystal substrates by chemical solution deposition. The results show that the derived CNC thin films are c-axis oriented regardless of the substrate orientation, suggesting the self-assembled c-axis orientation. The microstructures as well as the physical properties are investigated, showing that the CNC thin films are metallic and can be considered as a new type of soft-magnet with a ferromagnetic Curie temperature higher than 650 K. The results will provide an effective route for fabricating antiperovskite cobalt-based thin films as well as provide a prototype for the investigation of the growth mechanisms of complex metal nitride thin films by solution methods.
