MnN, CoN thin films were prepared by PLD, and the correlation between deposition conditions and crystal structure of the crystalline films was investigated. Synthesis of (Gd,La)N and (Mn,Co)N was also attempted. Cubic MnN with an abnormally large lattice constant (a=4.445(3) A) was grown on MgO for the first time. It was revealed that another cubic phase with a=4.2 A was formed as a main phase. Currie temperature of (Gd,La)N was controllable by the composition, and formation of crystalline CoN was sensitive to the substrate temperature.

通过PLD制备MNN，薄膜，并研究了沉积条件与晶体膜的晶体结构之间的相关性。还尝试了（GD，LA）N和（Mn，Co）N的合成。首次在MGO上生长具有异常大的晶格常数（A = 4.445（3）A）的立方MNN。揭示了另一个具有A = 4.2 A的立方相作为主要相。 （GD，la）N的Currie温度可通过组成控制，并且形成结晶粉对底物温度敏感。
