Abstract The Fe1─XMnX (0 ≤ x ≤ 0.39) nanowire (NW) arrays were synthesized through anodic aluminum oxide (AAO) template-based electrodeposition method. The elemental composition of the NWs was varied by changing the Mn-ions concentration in the electrochemical bath during electrodeposition. Energy Dispersive X-rays Spectroscopy (EDX) spectrums confirmed the Mn contents, that was increased in the NWs from 0 to 39 with respect to increase in Mn-ion concentration in the electrolyte. The X-ray diffraction (XRD) patterns exhibited the NWs were crystallized into the body-centered cubic (bcc) structure. Furthermore, the lattice parameter of NWs decreased as Mn content increased in the NWs whereas the increasing trend in grain size was observed. The magnetic properties of NWs were determined by recording MH-loops at room temperature with applied magnetic field in parallel ( ∥ ) and perpendicular ( ⊥ ) direction to the long-axis of NWs. The MH-loops revealed the existence of strong magnetic anisotropy and anisotropy field ( H k ) that was determined by the Anisotropy Field Distribution (AFD) method. A decreasing trend in the coercivity ( H c ), saturation magnetization ( M s ) and anisotropy field ( H k ) was observed as a function of Mn contents in FeMn NWs. The ZFC-FC curves were also recorded with 1kOe applied magnetic field, which demonstrated the ferromagnetic behavior and exhibited the blocking temperature was increased (Fe NWs ~ 300 K, Fe0.82Mn0.18 NWs ~ 330 K, and Fe0.61Mn0.39 NWs > 350 K) with the increase of Mn content. Moreover, the conductivity and mobility of the NWs were also decreased that were analyzed through four-probe Hall techniques.

通过在 AAO 模板中电沉积对 Fe1─XMnX (0 ≤ x ≤ 0.39) 合金纳米线进行结构、磁性和电学研究

摘要 Fe1─XMnX (0 ≤ x ≤ 0.39) 纳米线(NW) 阵列是通过基于阳极氧化铝(AAO) 模板的电沉积方法合成的。通过在电沉积过程中改变电化学浴中的 Mn 离子浓度来改变 NW 的元素组成。能量色散 X 射线光谱 (EDX) 光谱证实了锰含量，随着电解液中锰离子浓度的增加，锰含量从 0 增加到 39。X 射线衍射 (XRD) 图案显示 NW 结晶为体心立方 (bcc) 结构。此外，随着 NWs 中 Mn 含量的增加，NWs 的晶格参数降低，而观察到晶粒尺寸的增加趋势。NWs 的磁性是通过在室温下记录 MH-loops 来确定的，外加磁场平行 (∥ ) 和垂直 (⊥ ) 方向于 NWs 的长轴。MH 环揭示了强磁各向异性和各向异性场 (H k ) 的存在，这是由各向异性场分布 (AFD) 方法确定的。观察到矫顽力 (Hc)、饱和磁化强度 (Ms) 和各向异性场 (Hk) 呈下降趋势，这是 FeMn NW 中 Mn 含量的函数。ZFC-FC 曲线还记录了 1kOe 施加的磁场，这证明了铁磁行为并表现出阻塞温度升高（Fe NWs ~ 300 K、Fe0.82Mn0.18 NWs ~ 330 K 和 Fe0.61Mn0.39 NWs > 350 K) 随着 Mn 含量的增加。而且，
