Abstract

Trilayered ruthenate Sr4 Ru3 O10 exhibits an interesting itinerant metamagnetic transition for magnetic fields applied along in-plane directions. Our earlier work has revealed that this metamagnetic transition occurs via a phase separation process with magnetic domain formation. We recently performed systematic investigations on its magnetotransport properties and constructed a magnetic field-temperature (H-T) phase diagram. In the phase separated regime of the phase diagram, due to domain boundary scattering, the resistivity is increased and shows nonmetallic temperature dependence, while outside the phase separation regime, the system shows Fermi-liquid ground-state properties, i.e., ρ T2. The Fermi-liquid temperature is strongly suppressed near the metamagnetic transition. The transport properties in the mixed phase region are sensitive to the disorders, and the magnetoresistivity steps in this region are found to be suppressed by increasing the level of disorders. In addition, we discussed the possible mechanism of the metamagnetic transition of this material.
