Phys. Rev. Lett. 102, 136404 (2009) [4 pages]Inhomogeneous Magnetic Phases: A Fulde-Ferrell-Larkin-Ovchinnikov-Like Phase in Sr3Ru2O7See Also: Publisher's Note Received 15 October 2008; published 1 April 2009; publisher error corrected 3 April 2009 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 crystal-lattice symmetry. We propose that this is a magnetic analogue of the spatially inhomogeneous superconducting Fulde-Ferrel-Larkin-Ovchinnikov state. We show—through a Ginzburg-Landau expansion where the magnetization transverse to the applied field can become spatially inhomogeneous—that a Stoner model with electronic band dispersion can reproduce this phase diagram and transport behavior. © 2009 The American Physical Society URL:
