Data for “Spontaneous cycloidal order mediating a spin-reorientation transition in a polar metal"

Data for the manuscript “Spontaneous cycloidal order mediating a spin-reorientation transition in a polar metal" by C. D. Dashwood, L. S. I. Veiga, Q. Faure, J. G. Vale, D. G. Porter, S. P. Collins, P. Manuel, D. D. Khalyavin, F. Orlandi, R. S. Perry, R. D. Johnson, and D. F. McMorrow, Phys. Rev. B 102, 180410(R) (2020).<br>All the data is provided in text files, each containing a single header line followed by the data. All temperatures are in Kelvin, magnetic field strengths in Tesla, angles in degrees, and resistances in Ohms.<br>The parent folder contains the in-plane resistivity and powder XRD data.<br>Neutron scattering data is contained in the "Neutron" folder, with each file labelled by the magnetic field strength and Bragg peak (commensurate peak "001" or incommensurate satellite peak "d01").<br>Resonant x-ray scattering data is contained in the "X-ray" folder, under four subfolders for the azimuthal dependences ("Azi_deps"), energy dependences ("E_deps"), reciprocal space scans ("H_scans") and theta scans ("Th_scans"). Files in all the subfolders are labelled by the temperature and Bragg peak (commensurate peak "005" or incommensurate satellite peak "d05"), followed by further labels for the x-ray polarisation ("sig-sig" or "sig-pi"), azimuthal angle ("psi90" or "psi180") and absorption edge ("L2" or "L3"). The azimuthal dependences folder also contains a file "Parameters" with the fitted values of Ma and Mb (defined in the manuscript) and their errors.

本数据集对应C. D. Dashwood、L. S. I. Veiga、Q. Faure、J. G. Vale、D. G. Porter、S. P. Collins、P. Manuel、D. D. Khalyavin、F. Orlandi、R. S. Perry、R. D. Johnson与D. F. McMorrow发表于《物理评论B辑》(Phys. Rev. B) 102卷, 180410(R) (2020年) 的论文《极性金属中介导自旋重取向转变的自发摆线有序结构》。
所有数据均以文本文件形式提供，每个文件首行为标题行，后续为数据内容。所有温度单位为开尔文(K)，磁场强度单位为特斯拉(T)，角度单位为度(°)，电阻单位为欧姆(Ω)。
顶层文件夹包含面内电阻率与粉末X射线衍射（X-ray Diffraction, XRD）数据。
中子散射（Neutron scattering）数据存储于“Neutron”文件夹中，各文件以磁场强度与布拉格（Bragg）峰命名：共格布拉格峰“001”或非共格卫星峰“d01”。
共振X射线散射（Resonant x-ray scattering）数据存储于“X-ray”文件夹下的四个子文件夹中，分别对应方位角依赖性测量（"Azi_deps"）、能量依赖性测量（"E_deps"）、倒易空间扫描（"H_scans"）与θ角扫描（"Th_scans"）。各子文件夹内的文件以温度与布拉格峰（共格峰“005”或非共格卫星峰“d05”）命名，后续还附带X射线偏振态（“sig-sig”或“sig-pi”）、方位角（“psi90”或“psi180”）与吸收边（“L2”或“L3”）的标识。方位角依赖性测量子文件夹中还包含名为“Parameters”的文件，其内存储了论文中定义的Ma与Mb的拟合值及其误差。
