a Illustration of the TbFe/Pt/Co based magnetic multilayer with orthogonal magnetic easy-axis. b The out-of-plane Hall resistance loops of TbFe/Pt (1.2 nm)/Co sample. c Schematics of the field sweep measurements with tilt angle favoring and opposing the interlayer DMI (top left and right, respectively). The bottom diagram shows the geometry employed for the magnetoresistance measurements. d The Hall resistance curves of TbFe/Pt(1.5 nm)/Co measured during a field sweep at θB = 15° tilted along D×z (red line, initial φB = 315°) and along -D×z (black line, initial φB = 135°). e The coercivity difference ΔBc as a function of φB. f Magnetoresistance curves as a function of the in-plane field for two different orientations of MTbFe.
