a SAF sample schematics. b Static out-of-plane hysteresis loop measured by VSM. The green and orange lines represent the process that sweeps the magnetic field from negative to positive and from positive to negative, respectively. The switching fields of the minor loop in two sweeping branches are defined as Hup and Hdown, respectively. The RKKY coupling field Hex and the coercivity HC are extracted from Hup and Hdown.
