Inhomogeneous magnetic phases: a LOFF-like phase in Sr3Ru2O7 (2008)
Berridge, A. M., Green, A. G., Grigera, S. A., Simons, B. D.
The phase diagram of Sr3Ru2O7 contains a metamagnetic transition that bifurcates to enclose an anomalous phase with intriguing properties - a large resistivity with anisotropy that breaks the...
Formation of a Nematic Fluid at High Fields in Sr3Ru2O7 (2006)
Borzi, R. A., Grigera, S. A., Farrell, J., Perry, R. S., Lister, S. J. S., Lee, S. L., ...
In principle, a complex assembly of strongly interacting electrons can self-organise into a wide variety of collective states, but relatively few such states have been identified in practice. We...
Disorder-Sensitive Phase Formation Linked to Metamagnetic Quantum Criticality (2004)

Phase Bifurcation and Quantum Fluctuations in Sr3Ru2O7 (2004)
Green, A. G., Grigera, S. A., Borzi, R. A., Mackenzie, A. P., Perry, R. S., Simons, B. D.
The bilayer ruthenate Sr_3Ru_2O_7 has been cited as a textbook example of itinerant metamagnetic quantum criticality. However, recent studies of the ultra-pure system have revealed striking anomalies...
The de Haas-van Alphen effect across the metamagnetic transition in Sr$_3$Ru$_2$O$_7$ (2004)
Borzi, R. A., Grigera, S. A., Perry, R. S., Kikugawa, N., Kitagawa, K., Maeno, Y., ...
We report a study of the de Haas-van Alphen (dHvA) effect on the itinerant metamagnet Sr$_3$Ru$_2$O$_7$. Extremely high sample purity allows the observation of dHvA oscillations both above and below...
Rigid-Band Shift of the Fermi Level in a Strongly Correlated Metal: Sr(2-y)La(y)RuO(4) (2004)
Kikugawa, N., Mackenzie, A. P., Bergemann, C., Borzi, R. A., Grigera, S. A., Maeno, Y.
We report a systematic study of electron doping of Sr2RuO4 by non-isovalent substitution of La^(3+) for Sr^(2+). Using a combination of de Haas-van Alphen oscillations, specific heat, and resistivity...
Multiple first-order metamagnetic transitions and quantum oscillations in ultrapure (2004)
Perry, R. S., Kitagawa, K., Grigera, S. A., Borzi, R. A., Mackenzie, A. P., Ishida, K., ...
We present measurements on ultra clean single crystals of the bilayered ruthenate metal Sr3Ru2O7, which has a magnetic-field-tuned quantum critical point. Quantum oscillations of differing...

Momentum Resolved tunneling in a Luttinger Liquid (2003)
Grigera, S. A., Schofield, A. J., Rabello, S., Si, Q.
We consider momentum resolved tunneling between a Luttinger liquid and a two dimensional electron gas as a function of transverse magnetic field. We include the effects of an anomalous exponent and...
Angular dependence of the magnetic susceptibility in the itinerant metamagnet Sr3Ru2O7 (2003)
Grigera, S. A., Borzi, R. A., Julian, S. R., Perry, R. S., Maeno, Y., Mackenzie, A. P.
We report the results of a study of the di erential magnetic susceptibility of Sr3Ru2O7 as a function of temperature and magnetic elds applied at a series of angles to the ab plane. By analysing the...
Metamagnetic Quantum Criticality (2001)
Millis, A. J., Schofield, A. J., Lonzarich, G. G., Grigera, S. A.
A renormalization group treatment of metamagnetic quantum criticality in metals is presented. In clean systems the universality class is found to be of the overdamped, conserving (dynamical exponent...
Perry, R. S., Galvin, L. M., Grigera, S. A., Capogna, L., Schofield, A. J., Mackenzie, A. P., ...
We report the results of low temperature transport, specific heat and magnetisation measurements on high quality single crystals of the bilayer perovskite Sr3Ru2O7, which is a close relative of the...
The Bose-glass phase in twinned YBaCuO(123) (1998)
Grigera, S. A., Morre, E., Osquiguil, E., Balseiro, C., Nieva, G.
Using an extensive scaling analysis of the transport properties in twinned YBaCuO(123) crystals we have experimentally found the predicted change in the universality class of the Bose-glass to liquid...
