This work focuses on characterising the recently discovered room temperature multiferroic PZTFT, which has demonstrated some unusual properties. This investigation is done on both large scales (mm) the bulk ceramic - and small length scales (nm)within each grain that makes up the ceramic. The aim is to gain a detailed understanding of what properties the material has, Chapter 3: how the are connected, Chapter 4; how the respond to different stimuli - like electric and magnetic fields, Chapter 5. These properties are rationalised in terms of the Landau free energy expansion, which shown in Chapter 6, indicates the presence of a quadratic coupling term in this material.
