在Rh（001）衬底上制备了四方畸变的FeCo-Ti-N薄膜。FeCo-Ti-N薄膜厚度为23.5 nm，具有单轴垂直各向异性，c/a晶格畸变率达到1.08。各向异性常数（K-u）估计最小值为0.57 MJ.m（-3）（5.7 x 10（6）ergs.cm（-3））。这些结果表明，Ti和N添加元素的组合可以有效地诱导Rh底层上的FeCo基合金中的晶格畸变，并且晶格畸变增加K-u。(C)2015 AIP Publishing LLC.
Tetragonally distorted FeCo-Ti-N films were prepared on a Rh(001) underlayer. Uniaxial perpendicular anisotropy was observed for FeCo-Ti-N films with a thickness of 23.5 nm, and the c/a lattice distortion reached 1.08. The anisotropy constant (K-u) was estimated to be a minimum of 0.57 MJ.m(-3) (5.7 x 10(6) ergs.cm(-3)). These results show that the combination of Ti and N additive elements could be effective for inducing lattice distortion in FeCo-based alloys on a Rh under layer, and that the lattice distortion increases K-u.
