From: Controllable generation of interlayer Dzyaloshinskii-Moriya interactions in the L10-FePt/Pt/Fe multilayers for field-free magnetization switching

Fig. 3

a The representative CIMS curves for the FePt(4)/Pt(1.5)/Fe(1) film. b Field-free magnetization switching of FePt(4)/Pt(t)/Fe(1) films with different Pt thickness. c The MOKE images of the field-free magnetization switching in the FePt(4)/Pt(1.5)/Fe(1) device. The numbers on the right side are the amplitudes of the pulse current in mA. Red circles mark the nucleation sites that can be repeated when negative currents are applied during a magnetization switching.
