Abstract

Itinerant-electron metamagnetism in the bilayer ruthenate Sr3Ru2O7 is studied by c-axis magnetostriction measurements on a high-quality single crystal in magnetic fields up to 18 T and at temperatures down to 20 mK. The positive linear magnetostriction coefficient suggests an initial decrease of the magnetization under c-axis uniaxial pressure. A highly enhanced magnetic Gruneisen parameter Gamma(H) = 106 indicates a strong magnetoelastic coupling. The system is particularly sensitive to c-axis strain. (c) 2006 Elsevier B.V.
