Abstract
Sr3Ru2O7 (SRO327) is a material that, in the bulk, exhibits a strange metal phase via tuning of the magnetic field to a quantum critical point <!--[if gte msEquation 12]> style='font-family:"Cambria Math",serif;mso-ascii-font-family:"Cambria Math";

normal'>Hc~7.8Hc ∼ 7.8 T. Fabrication of thin filmed SRO327 allows access to mesoscale measurements of the strange metal phase reported in bulk samples. Initial magnetotransport measurements of nanowires patterned from SRO327 can confirm quality and robustness of the fabrication process through comparison with unpatterned larger areas of the film. Further measurements via shot noise offer a look at the nature of charge carriers in the strange metal when compared to the normal metal phase.
