Films of photomagnetic CoFe Prussian blue analogue on thin manganite substrates: Fabrication and characterization

Films of photomagnetic Prussian blue analogue KjCok[Fe(CN)6] (CoFe-PBA) were deposited on thin manganite substrates (La0.4Pr0.6)0.67Ca0.33MnO3 (LPCMO). When the CoFe-PBA was directly deposited on the LPCMO substrate, the photomagnetic properties of the CoFe-PBA were not present because of oxidation of the CoII to CoIII, which can be suppressed by using a buffer layer of the non-photomagnetic KjNik[Cr(CN)]6 (NiCr-PBA). The transport properties of the LPCMO are not affected by the light-induced changes in the CoFe-PBA.
