Abstract In order to investigate the structural, magnetic and electric properties, Co-based Co2Mn0.5Fe0.5Sn full Heusler compound nanowires were synthesized for the first time using alternating current (AC) deposition in anodized alumina oxide (AAO) templates. The half-metallicity, band gap and 100% spin polarization was also confirmed using the art of full potential linearized augmented plane wave methods (FP-LAPW) within density functional theory (DFT). The SEM images have confirmed the average diameter of templates and nanowires 62 nm and 58 nm respectively. The XRD confirms the formation of full Heusler alloy, L21 (A2 & B2 type disorder) type crystal structure. Energy dispersive X-ray spectroscopy (EDX) technique shows Tin (Sn) decreases whereas (Co, Fe & Mn) almost increases with increase in deposition potential. The M−H loops show the variation of coercivity and saturation magnetization with respect to deposition potential. Two probe I-V curves show that resistance decreases w.r.t deposition voltage. The resistivity and carrier concentration were decreased in a similar fashion w.r.t increased in deposition voltage where as mobility was increased with increase in deposition voltage which show the increment of the grain size and diminishing the scattering of electron in grain boundary. So we have done a great effort to study the effect of deposition voltage on crystal structure, composition, morphology, electric and magnetic properties of Co-based Co2Mn0.5Fe0.5Sn full Heusler compound nanowires. The spin properties in Co2Mn0.5Fe0.5Sn Heusler alloy is of great interest for their practical use which is vigorous study in present as well as in future spintronics devices.

在 AAO 模板中通过交流电沉积合成的 L 2 1 型 (Co 2 Mn 0.5 Fe 0.5 Sn) Heusler 合金纳米线的电子、磁性和半金属性能分析

摘要 为了研究结构、磁学和电学性能，首次在阳极氧化铝（AAO）模板中采用交流电沉积法合成了钴基Co2Mn0.5Fe0.5Sn全赫斯勒复合纳米线。使用密度泛函理论 (DFT) 中的全电位线性化增强平面波方法 (FP-LAPW) 的技术也证实了半金属性、带隙和 100% 自旋极化。SEM 图像已确认模板和纳米线的平均直径分别为 62 nm 和 58 nm。XRD 证实形成了完整的 Heusler 合金，L21（A2 和 B2 型无序）型晶体结构。能量色散 X 射线光谱 (EDX) 技术显示锡 (Sn) 减少，而 (Co、Fe 和 Mn) 几乎随着沉积电位的增加而增加。MH 回路显示矫顽力和饱和磁化强度相对于沉积电位的变化。两个探针 IV 曲线显示电阻降低了沉积电压。电阻率和载流子浓度以类似的方式降低，随着沉积电压的增加而增加，其中迁移率随着沉积电压的增加而增加，这表明晶粒尺寸增加并减少了晶界中电子的散射。因此我们做了大量的努力来研究沉积电压对Co基Co2Mn0.5Fe0.5Sn全赫斯勒复合纳米线的晶体结构、成分、形貌、电学和磁学性能的影响。Co2Mn0.5Fe0 中的自旋特性。
