Magnetic excitations in La1.2Sr0.8NiO4 and LaSrNiO4
The recent exciting observations in the magnetic excitation spectra of cobalt oxides that are isostructural to the prototypical high-temperature superconducting cuprates have... -
Spin Waves in Detwinned SrFe2As2
We propose to measure spin waves in detwinned SrFe2As2, combined with our data on detwinned BaFe2As2 this allows us to understand if magnetic excitations in the two systems can...
