Disorder-induced damping of spin excitations in Cr-doped BaFeAs
Marli R. Cantarino, Rafael M. P. Teixeira, R. Pakuszewski +9
In doped Hund's metals, such as the iron-based superconductors, effects like charge doping and chemical pressure are often considered the dominant factors. Partial chemical substit…
Incoherent electronic band states in Mn-substituted BaFeAs
Marli R. Cantarino, Kevin R. Pakuszewski, Björn Salzmann +8
Chemical substitution is commonly used to explore new ground states in materials, yet the role of disorder is often overlooked. In Mn-substituted BaFeAs (MnBFA), superc…
Damped spin excitations in a doped cuprate superconductor with orbital hybridization
O. Ivashko, N. E. Shaik, X. Lu +13
A resonant inelastic x-ray scattering (RIXS) study of overdamped spin-excitations in slightly underdoped LaSrCuO (LSCO) with and is presented. Th…
A resonant inelastic x-ray scattering study of the spin and charge excitations in the overdoped superconductor La1.77Sr0.23CuO4
C. Monney, T. Schmitt, C. E. Matt +5
We present a resonant inelastic x-ray scattering (RIXS) study of spin and charge excitations in overdoped La1.77Sr0.23CuO4 along two high-symmetry directions. The line shape of the…
Persistent high-energy spin excitations in iron pnictide superconductors
K. J. Zhou, Y. B. Huang, C. Monney +10
Motivated by the premise that superconductivity in iron-based superconductors is unconventional and mediated by spin fluctuations, an intense research effort has been focused on ch…
Intense paramagnon excitations in a large family of high-temperature superconductors
M. Le Tacon, G. Ghiringhelli, J. Chaloupka +17
In the search for the mechanism of high-temperature superconductivity, intense research has been focused on the evolution of the spin excitation spectrum upon doping from the antif…
