抄録

The Nd-Fe-B/La thin films were deposited on the Al2O3(0001) substrate in order to investigate the effect of rare earth overlayer on the coercivity Hc. Highly textured Nd2Fe14B grains were grown by inserting the Mo(111) single crystal buffer layer. By depositing the La overlayer onto Nd2Fe14B thin films and subsequently post-annealing at 470 °C, the Hc value increased from about 10.5 kOe to 15.0 kOe. The amount of Hc increase by the combination of the La coating and post-annealing was about 4.5 kOe. After the post annealing, La oxide (hcp La2O3) was formed in the La layer, which was confirmed by means of XRD and SIMS depth profile measurements.
