  Abstract We report a new hard magnetic phase in the Mn 65 Ga 35− x Al x system. A Mn 65 Ga 35 sample consisting of the D0 22 -type Mn 3 Ga phase exhibited a coercivity of 400 kA/m. The partial replacement of Ga with Al in the Mn 65 Ga 35 sample resulted in the formation of a new cubic phase with a Curie temperature of 680 K. This cubic phase exhibited a coercivity of 730 kA/m, which is higher than

  Based on the compound, low-energy ball milling technique, along with size-selection and annealing treatment are utilized to study the magnetic hardening and magnetic anisotropy inducement. It was found that milling can effectively improve the coercivity. With increasing the milling time to 210 min, the coercivity gradually increases from 0.8 kOe to a maximum value of 4.71 kOe for powders milled for

  摘要 最近，我们通过感应熔炼高纯Mn和Ga，然后在465°C下退火2天，成功制备了空间群为P4/mmm的L1 0-有序Mn 1.15 Ga合金。据报道，最高的实验室温饱和磁化强度 Ms 为 92 emu/g，居里温度和各向异性场估计分别为 595 K 和 6.3 T。在该化合物的基础上，利用低能球磨技术，结合尺寸选择和退火处理来研究磁硬化和磁各向异性诱导。发现铣削可以有效地提高矫顽力。随着研磨时间增加到 210 分钟，矫顽力逐渐从 0.8 kOe 增加到研磨 120 分钟的粉末的最大值 4.71 kOe，然后下降。将研磨 120 min 的粉末分级为不同尺寸后，矫顽力有不同程度的提高，小于 10 μm 的颗粒矫顽力可达 5.03 kOe。然而，随着球磨时间的延长，剩磁和磁化强度越来越差。465°C退火1分钟后，剩磁和磁化恢复，矫顽力没有太大损失，极大地提升了能量积，L1 0 -Mn 1.15
• Structural evolution and magnetic properties of L10-type Mn54.5Al45.5-xGax (x = 0.0, 15.0, 25.0, 35.0, 45.5) phase

  The intermetallic compounds Mn54.5Al45.5-xGax (x = 0.0, 15.0, 25.0, 35.0, 45.5) with L1(0) structure were prepared by melt-spinning and annealing. The structural and magnetic properties were investigated by means of X-ray diffraction, neutron powder diffraction and magnetic measurement. Al and Ga atoms are found to occupy both the 1a (0, 0, 0) and 1d (1/2, 1/2, 1/2) sites and show a preference occupation for the 1d site. It was found that the lattice parameter a slightly decreases, while c abnormally increases with the increase of Ga content x, which can be attributed to the fact that the Ga atom located at the 1d sites is larger than that of Al. The mass magnetization decreases from 134 emu/g to 91 emu/g at 5 K as x increases from 0.0 to 45.5 due to higher density of the alloys with Ga in comparison to the alloys with Al. A coercivity (iH(c)) value of 3.67 kOe and the maximum energy product (BH)(max) of 2.05 MGOe were obtained for Mn54.5Al30.5Ga15 sample. All the L1(0) samples show a Curie temperature (T-c) well above room temperature and the value of T-c decreases almost linearly from 644 K for Mn54.5Al45.5 to 578 K for Mn54.5Ga45.5 due to the decrease of ferromagnetic Mn-Mn interaction in the a-b plane. The observed magnetic properties are in accordance with the competing ferromagnetic interactions between Mn moments at the regular 1a site and antiferromagnetic coupling with the excess Mn atoms occupying the Ga (1d) site.

• Magnetic structure of γ-Mn(Ga) alloys with distorted cubic lattices

  gamma-Mn alloys containing Ga undergo a distortion from the face-centered-cubic structure to the face-centered-tetragonal structure with c/a < 1 or c/a > 1, depending on composition. The face-centered-orthorhombic structure also exists in a composition range between the two tetragonal phases. The antiferromagnetic structures of these phases have been determined by neutron-diffraction experiments. The tetragonal and orthorhombic phases exhibit collinear and noncollinear moments, respectively. The results are consistent with the theoretical prediction by Jo et al.
