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.

采用PLD法制备了MnN、CoN薄膜，研究了沉积条件与薄膜晶体结构的关系。还尝试了（Gd,La）N和（Mn,Co）N的合成。首次在MgO上生长出晶格常数异常大（a=4.445(3) a）的立方MnN。结果表明，主相形成了另一种立方相，a=4.2 a。（Gd,La）N的Currie温度可由组分控制，而晶体CoN的形成对衬底温度敏感。
