The experimental data obtained from single-electron tunneling measurements on Sr3Ru2O7, were reported. Tunneling measurements were carried out in a 3He cryostat using a standard four-probe technique. An unusual oscillation in tunneling magnetoresistance and a sharp change of the Fermi surface in tunneling spectra were observed near the metamagnetic transition in Sr3Ru2O7. The results show that single-electron tunneling might prove to be very effective means of studying quantum critical phenomena.
