| Research Abstract |
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.
