Heteroepitaxially enhanced magnetic anisotropy in BaTiO3- CoFe2O4 nanostructures
The authors have studied the magnetic properties of BaTi O3 -Co Fe2 O4 nanostructures, which were prepared using pulsed laser deposition. Such nanostructures show a large uniaxial magnetic anisotropy with an easy axis along the pillar long direction. As the growth temperature decreases, the magnetic anisotropy increases. Careful analyses reveal that heteroepitaxial strain is the primary contribution to the magnetic anisotropy. © 2007 American Institute of Physics.
