摘要 我们提出了一种方法，通过采用多样品方法，改进测量化学变异性对金刚石砧池中单晶样品物理性质的影响。通过使用聚焦离子束机定制样品的尺寸和形状，将相对较大的晶体同时加载到单个样品室中变得可行。为了说明这种方法的潜力，我们在高压下测量了具有不同化学成分的四种尖伍德石单晶的弹性性能。我们的结果表明，多样本方法可以量化化学变化（例如铁和氢的掺入）对物理性质的微小影响。此外，我们讨论了使用多样品方法将同一材料的具有不同晶体取向的多个晶体加载到一个样品室中的可能性，以便绘制各向异性物理性质的方向依赖性。
ABSTRACT We present a method to perform improved measurements of the effects of chemical variability on physical properties of single-crystal samples in the diamond-anvil cell by employing a multi-sample approach. By customizing the sizes and shapes of the samples using a focused ion beam machine the simultaneous loading of relatively large crystals into a single sample chamber becomes feasible. To illustrate the potential of this approach, elastic properties of four single crystals of ringwoodite with different chemical compositions have been measured at high pressure. Our results suggest that the multi-sample approach allows for the quantification of small effects of chemical variations, such as iron and hydrogen incorporation, on physical properties. Furthermore, we discuss the possibility of using the multi-sample approach to load several crystals with different crystallographic orientations of the same material into one sample chamber in order to map out the direction dependence of anisotropic physical properties.
