Evolution of Magnetism in Single-Crystal Ca2Ru1-xIrxO4 (0< x <0.65)
S. J. Yuan, J. Terzic, J. C. Wang +4
We report structural, magnetic, transport and thermal properties of single-crystal Ca2Ru1-xIrxO4 (0 < x< 0.65). Ca2RuO4 is a structurally-driven Mott insulator with a metal-insulat…
Novel magnetism of Ir5+ ions in the double perovskite Sr2YIrO6
G. Cao, T. F. Qi, L. Li +5
We synthesize and study single crystals of a new double-perovskite Sr2YIrO6. Despite two strongly unfavorable conditions for magnetic order, namely, pentavalent Ir5+(5d4) ions whic…
Ferromagnetic Exchange Anisotropy from Antiferromagnetic Superexchange in the Mixed 3d-5d Transition-Metal Compound Sr3CuIrO6
Wei-Guo Yin, X. Liu, A. M. Tsvelik +9
We report a combined experimental and theoretical study of the unusual ferromagnetism in the one-dimensional copper-iridium oxide SrCuIrO. Utilizing Ir edge resonant…
Dimensionality controlled Mott transition and correlation effects in single- and bi-layer perovskite iridates
Q. Wang, Y. Cao, J. A. Waugh +5
We studied Sr2IrO4 and Sr3Ir2O7 using angle-resolved photoemission spectroscopy (ARPES), making direct experimental determinations of intra- and inter-cell coupling parameters as w…
Strong magnetic instability in correlated metal Bi2Ir2O7
T. F. Qi, O. B. Korneta, Xiangang Wan +3
The interplay of spin-orbit interactions and electronic correlations dominates the physical properties of pyrochlore iridates, R2Ir2O7 (R = Y, rare earth element), which are typica…
Magnetic and Orbital Orders Coupled to Negative Thermal Expansion in Mott Insulators, Ca2Ru1-xMxO4 (M = Mn and Fe)
T. F. Qi, O. B. Korneta, S. Parkin +2
Ca2RuO4 is a structurally-driven Mott insulator with a metal-insulator transition at TMI = 357K, followed by a well-separated antiferromagnetic order at TN = 110 K. Slightly substi…
