Giant Spin Gap and Magnon Localization in the Disordered Heisenberg Antiferromagnet Sr2Ir1-xRuxO4
Yue Cao, Xuerong Liu, Wenhu Xu +15
We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr2Ir1-xRuxO4. A gigantic magnetic gap greater than 40 meV opens at x = 0.27 and in…
Magnetization reversal and negative volume thermal expansion in Fe doped Ca2RuO4
S. J. Yuan, T. F. Qi, J. Terzic +9
We report physical and structural properties of single-crystal Ca2Ru1-xFexO4 (0<x<0.20) as functions of temperature, magnetic field and pressure. Ca2RuO4 is a structurally-driven M…
Simultaneous Metal-Insulator and Antiferromagnetic Transitions in Orthorhombic Perovskite Iridate Sr0.94Ir0.78O2.68 Single Crystals
H. Zheng, J. Terzic, Feng Ye +7
The orthorhombic perovskite SrIrO3 is a semimetal, an intriguing exception in iridates where the strong spin-orbit interaction coupled with electron correlations tends to impose a…
Ground state tuning of the metal-insulator transition by compositional variations in BaIr1-xRuxO3(0<x<1)
S. J. Yuan, K. Butrouna, J. Terzic +5
BaIrO3 is a magnetic insulator driven by the spin-orbit interaction (SOI), whereas BaRuO3 is a paramagnet and exhibits a crossover from a metallic to an insulating regime. Our inve…
Coexisting charge and magnetic orders in the dimer-chain iridate Ba5AlIr2O11
J. Terzic, J. C. Wang, Feng Ye +7
We have synthesized and studied single-crystal Ba5AlIr2O11 that features dimer chains of two inequivalent octahedra occupied by tetravalent and pentavalent ions, respectively. Ba5A…
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…
