Magnetic quantum oscillations in YBa $_{2}$ Cu $_{3}$ O $_{6.61}$ and YBa $_{2}$ Cu $_{3}$ O $_{6.69}$ in fields of up to 85 T; patching the hole in the roof of the superconducting dome

John Singleton, Clarina de la Cruz, R. D. McDonald +8

We measure magnetic quantum oscillations in the underdoped cuprates YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ with $x = 0.61$ , 0.69, using fields of up to 85 T. The quantum-oscillation frequencies and…

Electronic self-organization in the single-layer manganite $P r_{1 - x} C a_{1 + x} Mn O_{4}$

F. Ye, Songxue Chi, J. A. Fernandez-Baca +7

We use neutron scattering to investigate the doping evolution of the magnetic correlations in the single-layer manganite $P r_{1 - x} C a_{1 + x} Mn O_{4}$ , away from the $x = 0.5$ …

Spin-Phonon Coupling in Iron Pnictide Superconductors

T. Egami, B. V. Fine, D. J. Singh +3

The magnetic moment in the parent phase of the iron-pnictide superconductors varies with composition even when the nominal charge of iron is unchanged. We propose the spin-lattice…

Resonance as a probe of the electron superconducting gap in BaFe1.9Ni0.1As2

Jun Zhao, Louis-Pierre Regnault, Chenglin Zhang +5

The discovery of high-transition temperature (high-Tc) superconductivity near antiferromagnetism in iron arsenides raised the possibility of an unconventional superconducting mecha…

Structural and magnetic phase transitions in Na $_{1 - δ}$ FeAs

Shiliang Li, Clarina de la Cruz, Q. Huang +5

We use neutron scattering to study the spin and lattice structures of single crystal and powder samples of Na $_{1 - δ}$ FeAs ( $T_{c} = 23$ K). On cooling from room temperature, the syst…

Spin gap and magnetic resonance in superconducting BaFe $_{1.9}$ NiAs $_{2}$

Shiliang Li, Ying Chen, Sung Chang +6

We use neutron spectroscopy to determine the nature of the magnetic excitations in superconducting BaFe $_{1.9}$ Ni $_{0.1}$ As $_{2}$ ( $T_{c} = 20$ K). Above $T_{c}$ the excitations are…
