Giant, pressure-induced magnetic switching in the ruthenate Sr4Ru3O10

ORAL

Abstract

The triple-layered Sr4Ru3O10 is a magnetic metal with a magnetic transition at 105 K and a low-spin S=1 state. It presents a strong ferromagnetic behavior along the magnetic easy-axis that is uncommonly aligned with the c-axis, but unusual antiferromagnetic and metamagnetic characteristics within the basal plane at ambient pressure. This sharply contrasts its sister compound, the ferromagnetic metal SrRuO3. The central findings of this work are that the application of relatively low pressures (up to 1 GPa) can readily switch the direction of magnetic moments from the c-axis to the basal plane, where the basal-plane magnetization is nearly saturated with an enhanced order moment of 0.8 Bohr magneton/Ru at 1 GPa and 2 Tesla. The magnetic switching also results in drastic changes in transport properties. All results will be presented and discussed along with comparison drawn with other related compounds.
