Investigating artificial multiferroic structures using polarised neutron reflectivity

Abstract: Multiferroic systems have more than one functionality, i.e. ferromagnetism, ferroelectricity, ferroelasticity and ferrotoroidicity. In nature there are few materials that display multiferroic behaviour, thus research has focused on artificial multiferroic systems, such as piezoelectric (PE) substrate with magnetostrictive (FM) films grown on top. It has been demonstrated that applying an electric field to the PE substrate can change the FM magnetisation from the easy direction to the hard direction. Further work has found that using thin layers between the PE substrate and the FM film can enhance the effect. It was also found that using FeSiB (amorphous magnetic material) as the midlayer introduced two different remnant magnetisation states, depending on whether a positive or negative E-field was applied. This proposal looks to use polarised neutrons to determine why two states occur.
