使用正电子湮灭技术，研究了Nd〓Fe〓B／α-Fe粉复合磁体的界面缺陷状态和矫顽力的关系。

Some methods, such as hydrothermal method, sol-gel method and pulse laser deposition method, have been developed to prepare manganite nanomaterials. Studies on the nanoscaled manganites revealed that they exhibit a number of novel physical properties such as low field high magnetoresistance, superparamagnetism, and large coercivity and more promising applications as compared to the corresponding bulk compounds.

发展了低温水热法、溶胶凝胶法、脉冲激光沉积模板法等方法制备锰氧化物纳米材料，研究发现纳米级的锰氧化物表现出了一些不同于块材的奇特的物理性质：如低场高磁阻效应、超顺磁性、大矫顽力、低饱和磁化强度及表面自旋玻璃等。

After the second aging, the microstructure doesn't change and the anisotropy field of ordered phase increases, it leads to an increase of the coercivity.

第二步时效处理后，PtCo合金的微观组织结构不发生改变，有序相的各向异性场增大，使合金的矫顽力增大。

The XRD result indicates that the axial ratio c/a of the tetragonal structure decreases with increasing the content of platinum, which leads to an increase of the deviation from unity of the tetragonal structure. So that, the anisotropy field of the ordered phase is improved and the coercivity is increased.

合金的X射线衍射结果表明：时效热处理后，随着Pt含量的增加，合金面心四方结构的有序相的c/a值逐渐减小，c/a值的减小增大了四方晶格结构的a与c方向的不对称性，使有序相的磁晶各向异性场增大，提高了合金的矫顽力

Considerating over-all performance of mag nets, it was concluded that the optimal amount of doped-Ga was 0.5wt%. The other was that the grains size distribution of grains was narrow and grain distributed homogeneously as to microstructure of magnets when the amount of doped-Ga was 1 .Owt%;(3 ) In the magnets, there existed not only Nd2Fei4-xGaxB, but also GaNd concerning the Ga-elment form. The GaNd increased the amount of liquid and had favorable function during sintering, so it made for the increase of magnets density and the form of the second phase is good for improving coercivity.

综合考虑磁体的性能，最终得出添加0.5wt％为最佳的Ga添加量；(2)对于Nd_(15)Fe_(78)B_7+Ga系永磁体，当Ga的添加量为1.0wt％时，得到颗粒粒度分布范围窄，颗粒分布较均匀的显微结构；(3)元素Ga在磁体中不但以Nd_2Fe_(14-x)Ga_xB形式存在，而且以GaNd的形式存在，在烧结的过程中，增加了液相的数量，起助烧结的作用，有利于磁体密度的提高，形成第二相有利于矫顽力的提高。

The magnetic coercive forces of deposits in the directions of parallel and perpendicular to the surface of deposits are similar.

不同组成钯铁合金镀层的垂直与平行两个方向的磁矫顽力差别不大。

Metal magnetic powder with fine particles and relative higher coercivity and remanence are ideal materials for high density magnetic recording .

金属磁粉颗粒细小，具有较高的矫顽力和剩磁，是较为理想的高密度磁记录材料。2。

For recording media, high density demands high coercivity while high readout S/N ratio demands high remanent magnetization.

就记录介质而言，高记录密度要求有高的矫顽力，高读出信噪比要求有高的剩余磁化强度。

However, W addition stabilizes the phase of 〓, which can weaken the exchange coupling between the nano-grains of magnetic phases, resulting in the decrease of the coercivity and rectangularity of magnets.

另一方面，添加W能够稳定分布于晶间的富硼相〓，该富硼相削弱磁性晶粒间的交换耦合，导致磁体矫顽力降低和矩形度变差。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
