The magnetic form factor of SrFe2As2

ORAL

Abstract

The Fe-pnictide based superconductors have recently been the subject of great interest. In this talk, we discuss recent neutron diffraction measurements of the magnetic form factor of SrFe2As2. These measurements reveal that while the form factor is primarily isotropic, a maximum entropy reconstruction reveals that there is evidence of hybridization between the Fe and As orbitals.
