Abnormal T-linear susceptibility and Phase diagram of BaFe $_{2 - x}$ Co $_{x}$ As $_{2}$ single crystals

X. F. Wang, T. Wu, G. Wu +4

We study systematically transport, susceptibility and heat capacity for BaFe $_{2 - x}$ Co $_{x}$ As $_{2}$ single crystals. In the underdoped region, spin density wave (SDW) transition is ob…

Transport properties and superconductivity in K $_{1 - x}$ Ln $_{x}$ Fe $_{2}$ As $_{2}$ (Ln=Sm, Nd and La) system

R. H. Liu, G. Wu, H. Chen +8

We prepared the samples K $_{1 - x}$ Ln $_{x}$ Fe $_{2}$ As $_{2}$ (Ln=Sm, Nd and La) with ThCr $_{2}$ Si $_{2}$ -type structure. These samples were characterized by X-ray diffraction, resistivity, sus…

Heat capacity measurements on FeAs-based compounds: a thermodynamic probe of electronic and magnetic states

P. J. Baker, S. R. Giblin, F. L. Pratt +7

We report heat capacity measurements of the pnictide materials SmFeAsO $_{1 - x}$ F $_{x}$ , NdFeAsO, LaFeAsO $_{1 - x}$ F $_{x}$ and LiFeAs. For SmFeAsO $_{1 - x}$ F $_{x}$ , with x close to 0.1, we use…

Superconductivity at 56 K in Samarium-doped SrFeAsF

G. Wu, Y. L. Xie, H. Chen +9

We synthesized the samples Sr $_{1 - x}$ Sm $_{x}$ FFeAs with ZrCuSiAs-type structure. These samples were characterized by resistivity and susceptibility. It is found that substitution of…

Doping-Driven Collapse of the SDW Correlation Gap in SmFeAsO $_{1 - x}$ F $_{x}$

Scott C. Riggs, R. D. McDonald, J. B. Kemper +8

We report the Hall resistivity, $ρ_{x y}$ of polycrystalline SmFeAsO $_{1 - x}$ F $_{x}$ for four different fluorine concentrations from the onset of superconductivity through the collap…

Probing multi-band superconductivity and magnetism in SmFeAsO $_{0.8}$ F $_{0.2}$ single crystals by high-field vortex torque magnetometry

L. Balicas, A. Gurevich, Y. J. Jo +9

To probe manifestations of multiband superconductivity in oxypnictides, we measured the angular dependence of magnetic torque $τ (θ)$ in the mixed state of SmO $_{0.8}$ F $_{0.2}$ FeAs…
