From: Magnetization Reversal by Out-of-plane Voltage in BiFeO3-based Multiferroic Heterostructures
Polarization and magnetization dynamics in CoFe dot/(110)-BiFeO3 island under voltage.
(a) Perpendicular voltage pulse applied on the poly-dot CoFe/(110)-island BFO multiferroic heterostructure. (b) Voltage pulses induced ferroelectric phase evolutions of 
and 
in BFO island 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.
