Hourglass dispersion and resonance of magnetic excitations in the superconducting state of the single-layer cuprate HgBa2CuO4+δ near optimal doping
M. K. Chan, Y. Tang, C. J. Dorow +8
We use neutron scattering to study magnetic excitations near the antiferromagnetic wave vector in the underdoped single-layer cuprate HgBa2CuO4+δ (superconducting transition temper…
Strong ferromagnetic exchange interaction in the parent state of the superconductivity in BaFeS
Meng Wang, S. J. Jin, Ming Yi +9
Inelastic neutron scattering measurements have been performed to investigate the spin waves of the quasi-one-dimensional antiferromagnetic ladder compound BaFeS, where a su…
Persistent Magnetism in Silver-doped BaFe2As2 Crystals
Li Li, Huibo Cao, David S. Parker +2
We investigate the thermodynamic and transport properties of silver-substituted BaFe2As2 (122) crystals, up to ~4.5%. Similar to other transition-metal substitutions in 122, Ag dim…
The magnetic precursor of the pressure-induced superconductivity in Fe-ladder compound
Songxue Chi, Yoshiya Uwatoko, Huibo Cao +4
The pressure effects on the antiferromagentic orders in iron-based ladder compounds CsFeSe and BaFeS have been studied using neutron diffraction. With identical cry…
