摘要：

Films of photomagnetic Prussian blue analogue KjCok[Fe(CN)(6)] (CoFe-PBA) were deposited on thin manganite substrates (La0.4Pr0.6)(0.67)Ca0.33MnO3 (LPCMO) to investigate whether the photoinduced changes of the CoFe-PBA can give rise to changes in the transport properties of the 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 Co-II to Co-III by the Mn in the substrate. The Co-II oxidation can be suppressed by using a buffer layer of the non-photomagnetic KjNik[Cr(CN)](6) (NiCr-PBA) between the CoFe-PBA and the LPCMO substrate. Using the buffer layer, the photomagnetic properties of the CoFe-PBA are recovered. Additionally, the transport properties of the LPCMO substrate are not affected by the light-induced changes in the CoFe-PBA. Published by Elsevier Ltd.
