Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
The study uses time‑resolved resonant inelastic X‑ray scattering to monitor how collective magnetic excitations (paramagnons) in an optimally electron‑doped cuprate superconductor…

Designing heterostructures to control oxygen stoichiometry in helimagnetic perovskite strontium ferrite
Jennifer Fowlie, Bernat Mundet, Danilo Puggioni +10
A large challenge in determining the physics of helimagnetic SrFeO3 is in stabilizing the stoichiometric chemical phase over long enough time scales to conduct extensive measuremen…

Biaxial Strain Control of Helimagnetism via Chemical Expansion in Thin Film SrFeO3
Jennifer Fowlie, Jiarui Li, Danilo Puggioni +15
We demonstrate control of helimagnetic order in biaxially strained SrFeO3 thin films using neutron diffraction and resonant soft x-ray scattering. SrFeO3, a negative charge-transfe…
