Stack structure, magnetic properties and domain patterns. a Schematic of stack structure with synthetic antiferromagnetic coupling and Dzyaloshinskii-Moriya interaction. b m-H curves for stack 1 and c stack 2. Blue and red colors denote the curves along out-of-plane and in-plane directions, respectively. d Magnetic domain patterns observed by magneto-optical polar Kerr effect microscopy under magnetic fields of −0.32, −0.2, 0, +0.2 mT, and +0.32 mT for stack 1
