The first-order phase transition observed at a moderate pressure of P=0.5 GPa between the insulating and the metallic high-pressure phase is characterized by a broad region of phase coexistence. The following structural changes are observed as function of pressure: (a) A discontinuous change of both the tilt and rotational angle of the RuO6-octahedra at this transition, (b) a gradual decrease of the tilt angle in the high-pressure phase (P>0.5 GPa), and (c) the disappearance of the tilt above 5.5 GPa leading to a higher symmetry structure. The magnetism was studied by single-crystal neutron diffraction: The ferromagnetic component of the high-pressure phase and a rearrangement of antiferromagnetic order in the low-pressure phase have been observed. 000051542 536__ $$0G:(DE-Juel1)FUEK245$$2G:(DE-HGF)$$aBetrieb und Weiterentwicklung der Neutronenquelle FRJ- 2$$cM05$$x0 000051542 536__ $$0G:(DE-Juel1)FUEK242$$aKondensierte Materie$$cM02$$x1 000051542 542__ $$2Crossref$$i2005-09-07$$uhttp://link.aps.org/licenses/aps-default-license 000051542 588__ $$aDataset connected to Web of Science 000051542 650_7 $$2WoSType$$aJ 000051542 7001_ $$0P:(DE-HGF)0$$aFriedt, O.$$b1 000051542 7001_ $$0P:(DE-HGF)0$$aMarshall, W.
