Polarization and magnetization dynamics in CoFe dot/(110)-BiFeO3 film under voltage.
(a) Perpendicular voltage pulse applied on the poly-dot CoFe/(110)-thin-film BFO multiferroic heterostructure. (b) Voltage pulses induced ferroelectric phase evolutions of 
, 
, 
and 
in BFO thin-film layer. (c) Voltage pulses induced interfacial HDM field and hence (d) the magnetization evolution in CoFe dots. Voltage-induced corresponding (e) polarization domain-vector morphology in x’-z’ middle cross-sectional plane of BFO-substrate layers, (f) the 
and (g) magnetization domain-vector morphologies in x’-y’ plane middle cross-sectional plane of CoFe layer, respectively. The color wheel indicates the P , 
, or m orientation in the their correspondingly exhibited planes.
