Nematicity in LaFeAsOF
C. Hess, H. Grafe, A. Kondrat +6
Orbital ordering has recently emerged as another important state in iron based superconductors, and its role for superconductivity as well as its connection to magnetic order and o…
Pr magnetism and its interplay with the Fe spin density wave in PrFeAsO
U. Stockert, N. Leps, L. Wang +4
We have studied the magnetism of the Pr3+ ions in PrFeAsO_1-xF_x (x = 0; 0.15) and its interaction with the Fe magnetic order (for x = 0). Specific heat data confirm the presence o…
Hole-doping in BaFeAs: The case of BaNaFeAs single crystals
S. Aswartham, M. Abdel-Hafiez, D. Bombor +11
Single crystals of BaNaFeAs with = 0, 0.25, 0.35, 0.4 were grown using a self-flux high temperature solution growth technique. The superconducting and norma…
Bond disorder and breakdown of ballistic heat transport in the spin-1/2 antiferromagnetic Heisenberg chain as seen in Ca-doped SrCuO2
N. Hlubek, P. Ribeiro, R. Saint-Martin +9
We study the impact of a weak bond disorder on the spinon heat transport in the S=1/2 antiferromagnetic (AFM) Heisenberg chain material Sr_{1-x}Ca_xCuO_2. We observe a drastic supp…
Phase diagram of iron-arsenide superconductors Ca(Fe1-xCox)2As2 (0 <= x <= 0.2)
L. Harnagea, S. Singh, G. Friemel +9
Platelet-like single crystals of the Ca(Fe1-xCox)2As2 series having lateral dimensions up to 15 mm and thickness up to 0.5 mm were obtained from the high temperature solution growt…
Scaling of normal-state transport properties of 1111 iron-pnictide superconductors
E. Arushanov, C. Hess, G. Behr +6
We show that the zero field normal-state resistivity above Tc for various levels of electron doping-both for underdoped, optimally, and overdoped LaO1-xFxFeAs, i.e. (x=0.05-0.075 a…
