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.}, keywords = {J (WoSType)}, cin = {IFF-INS}, ddc = {530}, cid = {I:(DE-Juel1)VDB341}, pnm = {Betrieb und Weiterentwicklung der Neutronenquelle FRJ- 2 / Kondensierte Materie}, pid = {G:(DE-Juel1)FUEK245 / G:(DE-Juel1)FUEK242}, shelfmark = {Physics, Condensed Matter}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000232228500033}, doi = {10.1103/PhysRevB.72.094104}, url = {https://juser.fz-juelich.de/record/51542}, }
