Raw data collected with Hall effect sensor holder and transmission electron microscope

This dataset is part of the original manuscript "Magnetic domain wall dynamics studied by in-situ Lorentz microscopy with aid of custom-made Hall-effect sensor holder" published in Ultramicroscopy. We built a custom-made holder with a Hall-effect sensor to measure the single point magnetic flux density inside a transmission electron microscope (TEM, JEM-F200, JEOL). The measurement point is at the same place as the sample inside the TEM. We utilized information collected with the Hall-effect sensor holder to study magnetic domain wall (DW) dynamics by in-situ Lorentz microscopy. We generated an external magnetic field to the sample using the objective lens (OL) of the TEM.本数据集隶属于发表于《超显微学报》（Ultramicroscopy）的原创研究手稿《借助定制霍尔效应传感器支架的原位洛伦兹显微术磁畴壁动力学研究》。我们研制了一款搭载霍尔效应传感器（Hall-effect sensor）的定制样品杆，用于在透射电子显微镜（Transmission Electron Microscope, TEM，型号JEM-F200，制造商JEOL）内部测量单点磁通量密度，该测量点位与TEM腔体内的样品处于同一位置。我们借助该霍尔效应传感器支架采集的实验数据，通过原位洛伦兹显微术开展磁畴壁（Magnetic domain wall, DW）动力学研究，并利用透射电子显微镜的物镜（Objective Lens, OL）为样品施加外磁场。
