Description of methods used for collection/generation of data: Methods information in related publication and Philippa M. Shepley's thesis http://etheses.whiterose.ac.uk/id/eprint/11758 2. Methods for processing the data: Image analysis on Kerr microscope images. Python scripts were used to measure the lengths swept out by moving domain walls during magnet field pulses. file naming information: ef02902s_0000V_ip00000Oe_700mV006s.png SampleName_TransducerVoltage_InPlaneField_OutOfPlaneFieldPulse.png (out of plane field pulse is has a size in mV and a duration in seconds. For this image naming convention Magnetic field pulse size [Oe] = 0.1437 * pulse size [mV] 3. Instrument- or software-specific information needed to interpret the data: Origin Pro for some files. 4. Standards and calibration information, if appropriate: For DMI type measurments OUt of Plane Field pulse calibration: magnetic field [Oe] = 0.1437 * pulse size [mV] 5. Environmental/experimental conditions: Room temperature, ambient conditions. 6. Describe any quality-assurance procedures performed on the data: Magnets were calibrated and tested. Measurements were repeated to check for consistency. 7. People involved with sample collection, processing, analysis and/or submission: Philippa M.
