Sr2Ru3O7 is an unusual metamagnetic system which shows a novel "electron nematic phase" (ENP) at temperatures less than about 1K when a magnetic field of 8T is applied along the c-axis. This ENP phase can be identified by transport and thermodynamic anomalies, however, no order parameter has been associated with the phase. When the magnetic field is moved away from the c-axis, the transport properties of Sr2Ru3O7 become very anisotropic. Here we propose to investigate whether this anisotropy is due to the low energy magnetic excitations becoming isotopic. If this were the case, it would show that the ENP behaviour is due to the unusual low energy excitations present.
