A magnetorheological sample environment is presented that allows for in situ magnetic field and shear flow during small-angle neutron scattering (SANS) measurements and is now available at the Institut Laue-Langevin (ILL). The setup allows performing simultaneous magnetorheological measurements together with the investigation of structural and magnetic changes on the nanometer length scale underlying the rheological response of ferrofluids. We describe the setup consisting of a commercial rheometer and a custom-made set of Helmholtz coils and show exemplarily data on the field and shear flow alignment of a dispersion of hematite nanospindles in water.

Institut Laue-Langevin 的原位磁流变 SANS 装置

提出了一种磁流变样品环境，该环境允许在小角度中子散射 (SANS) 测量期间进行原位磁场和剪切流，现在可在劳厄-朗之万研究所 (ILL) 获得。该设置允许同时进行磁流变测量，同时研究铁磁流体流变响应的纳米长度尺度上的结构和磁性变化。我们描述了由商业流变仪和一组定制的亥姆霍兹线圈组成的设置，并展示了赤铁矿纳米轴在水中分散体的场和剪切流对齐的示例性数据。图形摘要 提供了一个磁流变样品环境，该环境允许在小角中子散射 (SANS) 测量期间进行原位磁场和剪切流，现在可以在劳厄-朗之万研究所 (ILL) 获得。磁流变样品环境允许在小角度中子散射 (SANS) 测量期间进行原位磁场和剪切流，现在可在劳厄-朗之万研究所 (ILL) 获得。
