Abstract
X-ray absorption spectroscopy experiments of core@shell, photomagnetic, Prussian blue analogue heterostructures obtain local structure around the magnetic, transition metal ions before and after illumination. Two samples, containing nickel hexacyanochromate (Ni-Cr) and cobalt hexacyanoferrate (Co-Fe) in Ni-Cr@Co-Fe and Co-Fe@Ni-Cr geometries, were studied. Both materials display the well-known photoinduced valence tautomerism of cobalt ions for Co-Fe, accompanied by a large change in cobalt to nitrogen distances. Furthermore, these experimental results show a structural coupling between the photoactive Co-Fe layer to the passive Ni-Cr layer. Finally, the strain across the heterostructured interface in Co-Fe and Ni-Cr containing core@shell models is investigated with simulations that use custom potentials derived from density functional theory calculations.
