Thermal stability analysis in CoFe dot/(110)-BiFeO3 island.
(a) Energy profile as function of polarization orientation for single-domain BFO islands. (b) Energy polar plot for an in-plane magnetized CoFe dot with a size of 192 nm × 192nm × 192 nm when the polarization in the bottom single-domain BFO island is along the 
direction. (c) Thermal stability factors as function of the respective lateral sizes (length and width) of BFO and CoFe. The thermal stability can be obtained from the energy profile by extracting the barrier (Δf) between the adjacent energy minimal.
