Study of the electronic nematic phase of Sr${}_3$Ru${}_2$O${}_7$ with precise control of the applied magnetic field vector

Abstract

We report a study of the magnetoresistivity of high purity Sr${}_3$Ru${}_2$O${}_7$, in the vicinity of its electronic nematic phase. By employing a triple-axis (9/1/1T) vector magnet, we were able to precisely tune both the magnitude and direction of the in-plane component of the magnetic field (H${}_{\parallel }$). We report the dependence of the resistively determined anisotropy on H${}_{\parallel }$ in the phase, as well as across the wider temperature-field region. Our measurements reveal a high-temperature anisotropy which mimics the behaviour of fluctuations from the underlying quantum critical point, and suggest the existence of a more complicated phase diagram than previously reported.
