Research data supporting [Waveform Control Pulsed Field Magnetization of RE-Ba-Cu-O Bulk Superconducting Rings]. The Microsoft Excel file contains all data plotted in figures 2 to 7 in the main manuscript. For the pulsed field magnetization data, the sample was first cooled down from the normal state to the superconducting state then a pulsed field was applied to it. The values of trapped field shown in the data file are the values recorded at 15 seconds after applying each pulsed field. For the field cooling data, the sample was cooled from room temperature to 77 K, in an applied field of 1.5 T from a copper electromagnet, using a liquid nitrogen bath. The applied field was then removed and the trapped field profiles at 1.5 mm above the top and bottom surfaces of the sample were measured. See the main manuscript for more details.
