Abstract

Magnetically bistable solid solutions of Prussian blue analogues with chemical formulas of K _αNi _1-xCo _x[Fe(CN) ₆] _β•nH ₂O (Ni _1-xCo _xFe) and K _αCo _γ[Fe(CN) ₆] _y[Cr(CN) ₆] _1-y•nH ₂O (CoFe _yCr _1-y) have been synthesized and studied using mass spectrometry, Mössbauer spectroscopy, X-ray diffraction, temperature-dependent infrared spectroscopy, and dc magnetometry. These compounds provide insight into interfaces between the photomagnetic Co-Fe Prussian blue analogue and the high-T _C Ni-Cr Prussian blue analogue that exist in high-T _C photomagnetic heterostructures. This investigation shows that the bistability of Co-Fe is strongly modified by metal substitution, with Ni _1-xCo _xFe stabilizing high-spin cobalt-iron pairs and CoFe _yCr _1-y stabilizing low-spin cobalt-iron pairs, while both types of substitution cause a dramatic decrease in the bistability of the material.
