  Micelles-mediated synthesis of magnetic Fe3Pt nanoparticles of cubic morphology and their characterisation

  摘要：

  Development of a new synthetic route for the evolution of Fe3Pt particles with cubic morphology has been discussed here. These particles are expected to be applied for hyperthermia therapy due to their soft magnetic character because of a sharp fall of magnetic moment in the neighbourhood of 320 K. The soft magnetic property is due to their isotropic cubic morphology and structure. Published by Elsevier B.V.

  Abstract The tetragonality c / a of FCT martensite phase in an Fe 3 Pt depends on the degree of order S of the L1 2 -type parent phase. As the degree of order increases, the tetragonality c / a changes from being less than 1 ( S = 0.75) to being larger than 1 ( S = 0.88). In this study, we have investigated a martensitic transformation behavior in a single-crystalline Fe 3 Pt with a degree of order

  摘要 Fe 3 Pt 中FCT 马氏体相的四方性c / a 取决于L1 2 型母相的有序度。随着有序度的增加，四方性 c/a 从小于 1（S = 0.75）变为大于 1（S = 0.88）。在这项研究中，我们研究了有序度在 0.75 和 0.88 之间的单晶 Fe 3 Pt 中的马氏体转变行为，并发现 Fe 3 Pt 中存在斜方马氏体相。

  The magnetization of Fe 3 Pt Invar alloys with various long range order parameters has been measured in high magnetic fields up to 250 kOe. The relationship between the Curie temperature and the order parameter was obtained, and was interpreted in terms of the two γ states model, in which the excitation energy between the low spin states and the high spin states of Fe depends on the local environment

  已在高达 250 kOe 的高磁场中测量了具有各种长程有序参数的 Fe 3 Pt Invar 合金的磁化强度。获得了居里温度与有序参数之间的关系，并根据两个 γ 态模型进行了解释，其中 Fe 的低自旋态和高自旋态之间的激发能取决于 Fe 的局部环境原子。在无序的 Fe 3 Pt 合金中，非唯一的局部环境，即有序参数的不均匀性，会导致非线性阿罗特图。

  Magnetization, magnetostriction and magnetic anisotropy of Fe 3 Pt Invar alloys were investigated by changing the degree of long range order. The anomalous behaviour was found in magnetostriction and magnetic torque curves in the ordered Fe 3 Pt alloy at low temperatures. These anomalies are interpreted in terms of the reversible martensitic transformation caused by magnetic energy change.

  通过改变长程有序度研究了Fe 3 Pt Invar合金的磁化、磁致伸缩和磁各向异性。在低温下有序 Fe 3 Pt 合金的磁致伸缩和磁扭矩曲线中发现了异常行为。这些异常被解释为由磁能变化引起的可逆马氏体转变。

  Abstract The electrical resistivity of ordered Fe 3 Pt has been observed at high pressure up to 15 GPa. Above 4.5 GPa, T 2 dependence in the temperature dependent electrical resistivity is observed. The coefficients are found to increase with pressure and show a divergence near 16 GPa. This result indicates a quantum critical point near 16 GPa.

  摘要 在高达 15 GPa 的高压下观察到有序 Fe 3 Pt 的电阻率。高于4.5 GPa，观察到温度相关电阻率的T 2 相关性。发现系数随压力增加并在 16 GPa 附近显示发散。该结果表明在 16 GPa 附近有一个量子临界点。
