Multiferroics are materials which exhibit both electric and magnetic ordering simultaneously. Harnessing this is a single material above room temperature could potentially enable next generation electrical devices to be concieved which would offer faster write and save capabilities at a lower power cost. Bismuth ferrite is by the most studied multiferroic as both the electric and magnetic ordering temperatures are well above room temperature. However, depite extensive studies areas of the temperature dependent behaviour remain unclear. We would like to correlate the magnetic behaviour with the crystal structure in a temperature range of 500-900 K; an area which to date has recieved comparitively little attention. We believe this will enable us to shed light on some anomolous features which have been observed in the diffraction data.
