Raw hysteresis loops for this experiment are given in this folder in the file names starting with 'Ni in KOH'. Note that raw hysteresis loop files have the input voltage of the magnet as the first column, which can be converted into magnetic field in mT using the calibration equation field(mT)=3.94302*(field(V))-7.5804E-4. The suffix indicates the respective oxidation/reduction step in the graph (R=reduction, Ox=oxidation, OCP=open circuit potential). The exctracted coercivity values are given in the extra file 'Hc_over_cycles.txt'. The first column is the cycle number, the second the positive coercivity, the third the negative coercivity, the fourth the average coercivity, and the fifth the suffix of the corresponding hysteresis loop file. Average coercivity values are plotted in the graph as a function of cycle number.
