Spatially Resolved Strain-imprinted Magnetic States in an Artificial Multiferroic Physical Review B 86 (2012), 014408 Artificial multiferroic systems, in which novel properties can emerge from elastic coupling between
piezoelectric and magnetostrictive phases, are a promising route to obtain significant room-temperature
magnetoelectric coupling at the nanoscale. In this work, we have used element-specific soft x-ray photoemission
electron microscopy to spatially resolve the effects of ferroelectric BaTiO3 on the magnetic properties of
ferromagnetic layers of CoFe2O4 and NiFe2O4. Resulting from the large magnetoelastic anisotropy present
in these artificial multiferroic systems, a modification of the orientation and symmetry of the magnetic easy axes
of the ferromagnetic film upon changing the underlying domain structure of the ferroelectric has been observed.
This opens the possibility to strain-imprint magnetic states in these systems. View/Download |
