Dramatic Changes in the Electronic Structure Upon Transition to the Collapsed Tetragonal Phase in CaFe2As2
R. S. Dhaka, Rui Jiang, S. Ran +7
We use angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) calculations to study the electronic structure of CaFeAs in previously unexplor…
Crystallographic, Electronic, Thermal and Magnetic Properties of Single-Crystal SrCo2As2
Abhishek Pandey, D. G. Quirinale, W. Jayasekara +14
In tetragonal SrCo2As2 single crystals, inelastic neutron scattering measurements demonstrated that strong stripe-type antiferromagnetic (AFM) correlations occur at a temperature T…
Stripe Antiferromagnetic Spin Fluctuations in SrCoAs
W. Jayasekara, Y. Lee, Abhishek Pandey +12
Inelastic neutron scattering measurements of paramagnetic SrCoAs at T=5 K reveal antiferromagnetic (AFM) spin fluctuations that are peaked at a wavevector of $\textbf{Q…
Angle-Resolved Photoemission Spectroscopy Study of BaCo2As2
