Investigating Strain Effects on Helimagnetism in Cubic SrFeO₃ Thin Films

Cubic SrFeO₃ is a perovskite oxide (Pm-3̄m) with metallic conductivity and helimagnetic order. While its bulk magnetic properties are well known, the impact of strain on its magnetic behavior remains unclear. Using neutron and x-ray scattering, we probe how biaxial strain from the substrate modifies helimagnetic order in thin films. To better understand the underlying mechanisms, we are complementing these experiments with density functional theory (DFT) calculations. This work aims to clarify the relationship between lattice strain and complex magnetic order in perovskite oxides.
