Demagnetisation experiments raw data

This folder presents the measurement files of the alternating field (AF) and thermal (TH) demagnetisation experiments. The applied treatment is indicated with the name of the files. The information shown depends on the software and the settings of the laboratory in which the measurements were performed. Laboratory Grubenhagen of the Leibniz Institute for Applied Geophysics (*.DII files): sequential number, sample name, measurement type, measurement step, K (without specific meaning), Sm/M parameter, Intensity (mA/m), Inclination, Declination, X intensity, Y intensity, Z intensity Ebarhard Karls Universität Tuebingen (*.DAT files) showing "Sample ID", "AF Z" or "Temp C", "Intensity", "Declination: Unrotated", "Inclination: Unrotated" (background and tray correction applied as included in the measurement software longcore of 2G Enterprise) Eidgenössische Technische Hochschule ETH Zurich (*.DAT files) showing "Sample ID", "Intensity (emu)", "X corr", "Y corr", "Z corr", "Declination: Unrotated", "Inclination: Unrotated", "X Intensity", "Y Intensity", "Z Intensity", "X drift", "Y drift", "Z drift", "TH" (= Temperature step in °C), "comment", " AF Z (=AF step in Oe)" in different orders. During thermal demagnetisation the positions of the samples in the oven was not changed. The magnetic susceptibility was monitored after each thermal heating step. The values are provided in the files "MS(T)_Demag_Tuebingen.xlsx" and "MS(T)_Demag_Zurich.xlsx".

本文件夹包含交变场（alternating field, AF）与热退磁（thermal demagnetisation, TH）实验的测量文件。所采用的退磁处理方式由文件名标注。文件所展示的字段信息，取决于测量实施实验室的软件配置与实验参数设置。

莱布尼茨应用地球物理研究所格鲁本哈根实验室（*.DII格式文件）：其包含的字段依次为序列号、样品名称、测量类型、测量步长、无特定含义的K值、Sm/M参数、强度（单位：mA/m）、倾角、偏角、X轴强度、Y轴强度、Z轴强度。

蒂宾根大学埃伯哈德·卡尔斯学院（*.DAT格式文件）：其包含字段为“样品编号（Sample ID）”、“交变场强度（AF Z，单位：Oe）”或“温度（Temp C，单位：℃）”、“强度”、“未校正偏角（Declination: Unrotated）”、“未校正倾角（Inclination: Unrotated）”（背景与样品台校正已通过2G Enterprise公司的longcore测量软件自动完成）。

苏黎世联邦理工学院（ETH Zurich，*.DAT格式文件）：其包含字段顺序不固定，具体字段包括“样品编号（Sample ID）”、“强度（单位：emu）”、“X轴校正值（X corr）”、“Y轴校正值（Y corr）”、“Z轴校正值（Z corr）”、“未校正偏角”、“未校正倾角”、“X轴强度”、“Y轴强度”、“Z轴强度”、“X轴漂移量（X drift）”、“Y轴漂移量（Y drift）”、“Z轴漂移量（Z drift）”、“TH（即温度步长，单位：℃）”、“备注（comment）”、“AF Z（即交变场步长，单位：Oe）”。

热退磁实验过程中，样品在烘箱内的位置保持不变。每次热加热步骤后，均会对磁化率进行监测。磁化率监测数据已存储于“MS(T)_Demag_Tuebingen.xlsx”与“MS(T)_Demag_Zurich.xlsx”文件中。
