Abstract

We have studied the effect of hydrostatic pressure on the metamagnetic transition in Sr₃Ru₂O₇. For B⊥c, a peak in the magnetoresistance near the metamagnetic field B_M ≈ 5T suggests scattering due to strong fluctuations near a quantum critical point. On applying pressure, B_M increases linearly, extrapolating to B_M = 0 at a pressure p_c ≈ - 14 kbar. Scaling behaviour of the magnetoresistance with pressure suggests that the nature of the spin fluctuations is invariant under pressure. This demonstrates that spin fluctuations associated with the metamagnetism dominate the physics over a large region of pressure, temperature and field.
