Single hysteresis loop files during electrochemical measurements are labelled with the respective step (ox=oxidation, red=reduction + cycle number) and the applied potential during this step. The files dry.txt and OCP.txt give the hysteresis loops in the dry state and at the open circuit potential (OCP) after filling the cell with the electrolyte. Extracted coercivity values are given in the file 'Hc_1000_cycles.txt'. The total experiment was conducted in 2 days, a second hysteresis loop at OCP (OCP_2.txt) was recorded before restarting the measurement after day 1 after 200 cycles.
