N2 - Ba2FeNbO6 (BFNO) is an antiferromagnetic insulator with a Néel temperature TN of 25 K. We have systematically studied the effect of substrate on the electrical transport of this compound under different growth conditions. We find that while the bulk and thin films grown on LaAlO3 and NdGaO3 substrates are insulating, the film grown on SrTiO3 substrate shows metallic behaviour. The anomalous behaviour of this compound on SrTiO3 is attributed to the defect conduction of SrTiO3 induced by the film growth conditions.
