N2 - We report a search for new physics signals using the low energy electron recoil events in the complete data set from PandaX-II, in light of the recent event excess reported by XENON1T. The data correspond to a total exposure of 100.7 ton·day with liquid xenon. With robust estimates of the dominant background spectra, we perform sensitive searches on solar axions and neutrinos with enhanced magnetic moment. It is found that the axion-electron coupling gAe < 4.6 × 10-12 for an axion mass less than 0.1 keV/c2 and the neutrino magnetic moment μν < 4.9 × 10-11 μB at 90% confidence level. The observed excess from XENON1T is within our experimental constraints.
