Quantum Oscillations in the Anomalous Phase in Sr<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>

We report measurements of quantum oscillations detected in the putative nematic phase of Sr<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>. Improvements in sample purity enabled the resolution of small amplitude de Haas--van Alphen (dHvA) oscillations between two first or...

description We report measurements of quantum oscillations detected in the putative nematic phase of Sr<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>. Improvements in sample purity enabled the resolution of small amplitude de Haas--van 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 on domains.
