Temperature dependence of the resonant tunneling fields in high-spin molecules

The temperature dependence of the resonant tunneling fields in two Mn-based high spin molecules samples such as S=10 and S=9 was discussed. The shift of the resonant field in different step index and its temperature dependence from the mean field were explained. It was shown that when the temperature dependence of the observed resonant fields was taken into account, the mean field interaction, were fitted well with only a single-state tunneling. It was found that the upward shift of the small step-index resonant felds and the downward shift of the large step-index resonant fields were due to mutual interactions.
