Abstract
The observations that films that are antiferromagnetic (AF) at room temperature become uncoupled (or ferromagnetic) upon cooling, and that the AF coupling can be restored by intense laser irradiation, indicate that the FeSi spacer is semi-conducting with a small energy gap. An implication of this is that charge and spin carriers in the spacer are essential for the AF coupling. Mossbauer spectroscopy as well as structural and thermodynamic considerations implicate ε-FeSi as the spacer-medium species that controls the physics of interest.
