Effects of a magnetic field on the fragile antiferromagnetism in YbBiPt
B. G. Ueland, A. Kreyssig, E. D. Mun +13
We present neutron diffraction data for the cubic-heavy-fermion YbBiPt that show broad magnetic diffraction peaks due to the fragile short-range antiferromagnetic (AFM) order persi…
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…
Neutron Scattering Studies of the Ferroelectric Distortion and Spin Dynamics in the Type-1 Multiferroic Perovskite Sr0.56Ba0.44MnO3
Daniel K. Pratt, Jeffrey W. Lynn, James Mais +4
The magnetic order, spin dynamics, and crystal structure of the multiferroic Sr0.56Ba0.44MnO3 have been investigated using neutron and x-ray scattering. Ferroelectricity develops a…
Neutron-scattering measurements of the spin excitations in LaFeAsO and Ba(FeCo)As: Evidence for a sharp enhancement of spin fluctuations by nematic order
Qiang Zhang, Rafael M. Fernandes, Jagat Lamsal +11
Inelastic neutron scattering was employed to investigate the impact of electronic nematic order on the magnetic spectra of LaFeAsO and Ba(FeCo)As. T…
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…
Fragile antiferromagnetism in the heavy-fermion compound YbBiPt
B. G. Ueland, A. Kreyssig, K. Prokeš +12
We report results from neutron scattering experiments on single crystals of YbBiPt that demonstrate antiferromagnetic order characterized by a propagation vector, =…
