PFM and CAFM Measurements on BFO Thin Film

Simultaneous PFM and CAFM measurements on BFO thin film 

The PFM signals of amplitude (Left) and phase (Middle) with an applied AC sample bias of 1 V were measured simultaneously with current across the domain walls of a BFO thin film sample with an applied DC bias of 3 V using Swap mode. This method minimizes artifacts due to electrostatic force. 3 µm scan.
