| Abstract | We observe a large magneto-resistance in very thin Ba2FeMoO 6 films of ∼-12% at 10K, which is not significantly changed when thin NiFe/Ba2FeMoO6 bi-layers are made. This suggests that the magneto-resistance in both cases is dominated by inter-grain tunnelling in the Ba2FeMoO6 thin film. There is an anomalous peak in the resistance at ∼300K in the bi-layer film that can not be easily explained. However, we know that the temperature where this peak occurs is close to the Ba2FeMoO6 Curie temperature. © (2012) Trans Tech Publications, Switzerland. |
