Emergence of spinons in layered trimer iridate Ba4Ir3O10
Y. Shen, J. Sears, G. Fabbris +13
Spinons are well-known as the elementary excitations of one-dimensional antiferromagnetic chains, but means to realize spinons in higher dimensions is the subject of intense resear…
Charge ordering in Ir dimers in the ground state of BaAlIrO
Vamshi M. Katukuri, Xingye Lu, D. E. McNally +8
It has been well established experimentally that the interplay of electronic correlations and spin-orbit interactions in Ir and Ir oxides results in insulating J$_{\r…
Magnetic excitations in hole-doped Sr2IrO4: A comparison with electron-doped cuprates
J. P. Clancy, H. Gretarsson, M. H. Upton +3
We have studied the evolution of magnetic and orbital excitations as a function of hole-doping in single crystal samples of Sr2Ir(1-x)Rh(x)O4 (0.07 < x < 0.42) using high resolutio…
Anomalous Magnetic Behavior in Ba2CoO4 with Isolated CoO4 Tetrahedra
Qiang Zhang, Guixin Cao, Feng Ye +9
The dimensionality of the electronic and magnetic structure of a given material is generally predetermined by its crystal structure. Here, using elastic and inelastic neutron scatt…
Spin Density wave instability in a ferromagnet
Yan Wu, Zhenhua Ning, Huibo Cao +7
Ferromagnetic (FM) and incommensurate spin-density wave (ISDW) states are an unusual set of competing magnetic orders that are seldom observed in the same material without applicat…
Strong anisotropy within a Heisenberg model in the J=1/2 insulating state of Sr2Ir0.8Ru0.2O4
S. Calder, J. W. Kim, A. E. Taylor +5
The dispersive magnetic excitations in Sr2IrO4 have previously been well described within an isospin-1/2 Heisenberg model on a square lattice that revealed parallels with La2CuO4.…
