Spin transport in benzofurane bithiophene based organic spin valves. Palosse, M., Seguy, I., Bedel-Pereira, E., Villeneuve-Faure, C., Mallet, C., Frere, P., Warot-Fonrose, B., Biziere, N., & Bobo, J. Aip Advances, 4(1):017117, January, 2014. WOS:000331209400017doi abstract bibtex In this paper we present spin transport in organic spin-valves using benzofurane bithiophene (BF3) as spacer layer between NiFe and Co ferromagnetic electrodes. The use of an AlOx buffer layer between the top electrode and the organic layer is discussed in terms of improvements of stacking topology, electrical transport and oxygen contamination of the BF3 layer. A study of magnetic hysteresis cycles evidences spin-valve behaviour. Transport properties are indicative of unshorted devices with non-linear I-V characteristics. Finally we report a magnetoresistance of 3% at 40 K and 10 mV in a sample with a 50 nm thick spacer layer, using an AlOx buffer layer. (C) 2014 Author(s).
