Topological PdBi half-Heusler semimetals: a new family of non-centrosymmetric magnetic superconductors
Yasuyuki Nakajima, Rongwei Hu, Kevin Kirshenbaum +9
We report superconductivity and magnetism in a new family of topological semimetals, the ternary half Heusler compounds PdBi ( : rare earth). In this series, tuning of the ra…
Crossover from spin-waves to diffusive spin excitations in underdoped Ba(FeCo)As
G. S. Tucker, R. M. Fernandes, D. K. Pratt +12
Using inelastic neutron scattering, we show that the onset of superconductivity in underdoped Ba(FeCo)As coincides with a crossover from well-defined spin…
The non-magnetic collapsed tetragonal phase of CaFe2As2 and superconductivity in the iron pnictides
J. H. Soh, G. S. Tucker, D. K. Pratt +8
The relationship between antiferromagnetic spin fluctuations and superconductivity has become a central topic of research in studies of superconductivity in the iron pnictides. We…
Separation of antiferromagnetism and high-temperature superconductivity in CaLaFeAs under pressure
Shanta R. Saha, T. Drye, S. K. Goh +9
We report the effect of applied pressures on magnetic and superconducting order in single crystals of the aliovalent La-doped iron pnictide material CaLaFeAs$_{…
Magnonlike dispersion of spin resonance in Ni-doped BaFeAs
M. G. Kim, G. S. Tucker, D. K. Pratt +10
Inelastic neutron scattering measurements on Ba(FeNi)As manifest a neutron spin resonance in the superconducting state with anisotropic dispersion withi…
Competition between stripe and checkerboard magnetic instabilities in Mn-doped BaFe2As2
G. S. Tucker, D. K. Pratt, M. G. Kim +12
Inelastic neutron scattering measurements on Ba(Fe0.925Mn0.075)2As2 manifest spin fluctuations at two different wavevectors in the Fe square lattice, (1/2,0) and (1/2,1/2), corresp…
