We report recent transport and thermodynamic experiments over a wide range of temperatures for the Mott-like system Ca 3 Ru 2 O 7 at high magnetic fields, B (⩽ 30 T). This work reveals a rich and highly anisotropic phase diagram, where applying B along the a-, b-, and c-axis leads to vastly different behaviour. A fully spin-polarized state via a first-order metamagnetic transition is obtained for B⩾ 6 T and B|| a, and colossal magnetoresistance is seen for B|| b, and quantum oscillations in the resistivity are observed for B|| c, respectively. The interplay of the lattice, orbital and spin degrees of freedom are believed to give rise to this strongly anisotropic behaviour.
