项目摘要
In the study, an improvement in magnetic properties of anisotropic and isotropic Nd-Fe-B film magnets was carried out by using additives. In addition, several applications comprising the films were investigated. The obtained results are as followed.(1) Anisotropic Nd-Fe-B filmsAn obtained film prepared from the Nd_<2.4>Fe_<14>B+Ga_<0.5at.%> target had the coercivity, remanence and (BH)_<max> values of approximately 850 kA/m, 0.95 T and 150 kJ/m^3, respectively. These magnetic properties are superior compared with those for the anisotropic PLD-made Nd-Fe-B films without additives. We also confirmed that the intensities of a X-ray diffraction peaks corresponding to the c-planes such as (004), (006) and (008) of the film were stronger than those of the additive-free film.(2) Isotropic film magnetsPLD-made isotroipic Nd-Fe-B thick film magnets were prepared from targets with Zr, Nb and Ga, respectively. They were crystallized by two annealing methods of conventional annealing (CA) and pulse annealing (PA), respectively. In the case of using Nd_<2.6>Fe_<14>B targets, 0.5 at.% Zr, Nb and Ga addition increased the coercivity of the film by approximately 100~300 kA/m compared with that of additive-free samples prepared by CA method. We also confirmed further increase in coercivity of the film by PA method and the obtained film prepared from a Nd_<2.6>Fe_<14>B+Ga_<0.5at.%> target had large coercivity of approximately 1700 kA/m.(3) ApplicationsWe applied the above-mentioned films to a friction-drive motor and a milli-size motor.
通过添加添加剂对各向异性和各向同性的NdFeB薄膜磁体的磁性能进行了改善。此外,还研究了组成该薄膜的几种应用。(1)各向异性Nd-Fe-B薄膜用Nd_<;2.4>;Fe_<;14>;B+Ga_<;0.5at.%>;靶制备的薄膜具有约850kA/m、0.95T和150kJ/m的矫顽力、剩磁和(BH)_lt;max>;与未添加添加剂的各向异性PLD法制备的Nd-Fe-B薄膜相比,这些磁性能更优越。我们还证实了薄膜的(004)、(006)和(008)晶面对应的X射线衍射峰的强度比没有添加添加剂的薄膜的强度要大。(2)各向同性薄膜磁体分别以含Zr、Nb和Ga的靶材为原料制备了各向同性薄膜磁体。分别采用常规退火法(CA)和脉冲退火法(PA)进行了晶化处理。在使用Nd2.6>;Fe;14>;B靶的情况下,添加0.5at.%的Zr、Nb和Ga使薄膜的矫顽力比用CA法制备的样品提高了约100~300kA/m。我们还证实了用PA方法进一步提高了薄膜的矫顽力,由Nd_<;2.6>;Fe_<;14>;B+Ga_<;0.5at.%>;靶制备的薄膜具有很大的矫顽力,约为1700kA/m。(3)应用我们将上述薄膜应用于摩擦驱动电机和毫米级电机。
