Abstract:
We report on the combination of piezoresponse force microscopy (PFM), magnetic force microscopy,
and local ferroelectric switching with magnetic field for the study of a thin-film magnetoelectric (ME)
nanocomposite. The collection of PFM under an applied variable magnetic field within a
polycrystalline perovskite-spinel BiFeO3-CoFe2O4 (BFO-CFO) 0-3 type thin-film nanocomposite
enables quantitative and proximal measurement of magnetoelastic strain-driven ME response.
Combination of measurement of the as-grown strain state with local measurements of microstructure
and macroscopic magnetization permits local mapping of ME coupling.
