Abstract
Measuring the resistivity of high-purity single crystals of Sr_{3}Ru_{2}O_{7} under pressure, we find strong evidence that the field-induced spin density wave phase at the H ∥ c metamagnetic transition is suppressed at a surprisingly low pressure of ∼ 3 ± 1 kbar. This offers the possibility of studying a bare quasi-two-dimensional spin density wave quantum critical point, testing the T → 0 K limit of theories of Planckian dissipation and quantum criticality. Preliminary attempts to fit ρ(T) with a quantum critical spin fluctuation model, while encouraging, reveal a need for further, complementary measurements.
