Here, we report the effect of oleylamine (OLA) stabilizing molecules on the stability of iron-iron oxide core-shell nanoparticles in the electron beam. The presence of excess OLA (>50 wt%) induces the structural transformation in the highly crystalline, core-shell structures to form hollow iron oxide nanoparticles after 120 s of electron beam exposure.
