本研究借由实验探讨个别铁镓奈米线在有或没有外加偏磁场时之弹性性质。实验进行了一个定制的机械手阶段，设计用于扫描电子显微镜，其中纳米线进行机械测试静态和动态。实验中还进行了一个20 Oe直流磁场的存在下，以确定任何变化的电线性能。结果表明，铁镓纳米线具有非常相似的宏观尺度值的弹性模量，拉伸强度的两倍以上的散装材料，和轻微的磁场诱导硬化在低应力。
This study experimentally investigates the elastic properties of individual iron-gallium nanowires with and without an applied magnetic bias field. The experiments were conducted with a custom manipulator stage designed for use within a scanning electron microscope, where nanowires were mechanically tested both statically and dynamically. Experiments were also performed in the presence of a 20 Oe dc magnetic field in order to identify any variation in wire properties. The results suggest that iron-gallium nanowires possess an elastic modulus very similar to the macroscale value, tensile strengths of more than double the bulk material, and minor magnetic field induced stiffening at low stresses.
