Resumen:
We report measurements of quantum oscillations detected in the putative nematic phase of Sr3 Ru2 O7. Improvements in sample purity enabled the resolution of small amplitude de Haas­van Alphen (dHvA)oscillations between two first order metamagnetic transitions delimiting the phase. Two distinct frequencies were observed, whose amplitudes follow the normal Lifshitz-Kosevich profile. Variations of the dHvA frequencies are explained in terms of a chemical potential shift produced by reaching a peak in the density of states, and an anomalous field dependence of the oscillatory amplitude provides information ondomains.
