The ternary-arsenide compound BaCo2As2 was previously proposed to be in proximity to a quantum-critical point where long-range ferromagnetic (FM) order is suppressed by quantum fluctuations. Here we report the effect of Ir substitution for Co on the magnetic and thermal properties of Ba[Co(1-x)Ir(x)]2As2 (0 = 0.11 with a nearly composition-independent Curie temperature TC = 13 K. The small variation of TC with x, the occurrence of hysteresis in magnetization versus field isotherms at low field… Expand


Physical and magnetic properties of Ba(Fe1-xMnx)(2)As-2 single crystals
Single crystals of Ba(Fe1 xRux)2As2 ,x 0:2 and continues through the highest doping levels we report. The superconducting region is dome like, with maximum Tc ( 16:5 K) found around x 0:29. A phaseExpand
Superconducting state in SrFe2-xCoxAs2 by internal doping of the iron arsenide layers.
This first observation of bulk superconductivity induced by electron doping in this family of compounds-despite strong disorder in the Fe-As layer-favors an itinerant electronic theory in contrast to the strongly correlated cuprates and renders a p- or d-wave pairing unlikely. Expand
Structural and magnetic studies of Sr2IrO4.
The discovery of high-temperature superconductivity in doped copper oxides, which in their insulating forms are nearly ideal two-dimensional spin-1/2 Heisenberg antiferromagnets, has stimulated greatExpand
Ba(1-x)K(x)Mn2As2: an antiferromagnetic local-moment metal.
Ba(1-x)K(x)Mn2As2 is thus the first metallic ThCr2Si2-type MAs-based system containing local 3d transition metal M magnetic moments, with consequences for the ongoing debate about the local-moment versus itinerant pictures of the FeAs- based superconductors and parent compounds. Expand
Anomalous Composition-Induced Crossover in the Magnetic Properties of the Itinerant-Electron Antiferromagnet Ca_{1-x}Sr_{x}Co_{2-y}As_{2}.
A major finding is an anomalous magnetic behavior in the crossover region 0.2≲x≲0.3 between these two phases of composition-induced change in AFM structure. Expand
Absence of superconductivity in hole-doped BaFe2 xCrxAs2 single crystals
We investigate the physical properties and electronic structure upon Cr doping in the iron arsenide layers of BaFe{sub 2}As{sub 2}. This form of hole doping leads to suppression of theExpand
What controls the phase diagram and superconductivity in Ru-substituted BaFe2As2?
It is found that substitution of Ru for Fe is isoelectronic, i.e., it does not change the value of the chemical potential, and it is speculated that this mechanism relies on magnetic dilution which leads to the reduction of the effective Stoner enhancement. Expand
Physical and magnetic properties ofBa(Fe1−xRux)2As2single crystals
Single crystals of Ba(Fe1−xRux)2As2 , x < 0.37, have been grown and characterized by structural, magnetic and transport measurements. These measurements show that the structural/magnetic phaseExpand
Flat-band magnetism and helical magnetic order in Ni-doped SrCo2As2
A series of Sr(Co$_{1-x}$Ni$_x$)$_2$As$_2$ single crystals was synthesized allowing a comprehensive phase diagram with respect to field, temperature, and chemical substitution to be established. OurExpand
Competing magnetic ground states in nonsuperconducting Ba(Fe1-xCrx)2As2 as seen via neutron diffraction
We present neutron diffraction measurements on single-crystal samples of nonsuperconducting Ba(Fe{sub 1-x}Cr{sub x}){sub 2}As{sub 2} as a function of Cr doping for 0 {le} x {le} 0.47. The averageExpand
