(a) Experimental results on the relation between Vin ≡ VDC and Vout ≡\(V_{ME}^{1st}\) when HDC = 10Oe, HAC = 10Oe and the frequency of the AC field is 112 Hz. The purple and orange lines represent scanning Vin ≡ VDC from + 200 to − 200 V and from − 200 to + 200 V respectively. (b) The purple and orange lines are simulation results on \(V_{ME}^{1st}\) as a function of VDC at a fixed DC magnetic field corresponding to 0.5 HDC/HK that is read out from the circuit in Fig. 2b when the back-voltage constant is + vm and − vm respectively. Since our simulation does not capture a voltage controlled ferroelectric polarization switching, positive and negative vm values had to be used in the simulation. The arrows indicate how Vout versus Vin would behave once polarization switching is considered. Note that for the normalized \({V}_{ME}^{1st}\) the actual value of the back-voltage vm does not change the simulation results.
