Abstract : Single crystals and polycrystalline samples of FeWO4 were prepared and characterized. From high temperature paramagnetic data, the presence of high spin state Fe(+2)(3d6) was confirmed. Qualitative Seebeck measurements indicated p-type conductivity. The measured room temperature resistivity of single crystals was approx. 100 ohm-cm with an activation energy of .16(2) eV. No appreciable photocurrents were found in 0.2M NaAc at pH = 8.3. (Author)
