We investigated theoretically the magnetization reversal via vortex nucleation and annihilation in double-layer ferromagnetic/antiferromagnetic cylindrical dots. The influence of the antiferromagnetic layer on the magnetization reversal is accounted for by means of an interfacial, unidirectional exchange field. We consider explicitly a nonuniformity of the magnetization reversal mode along the direction perpendicular to the layers, which gives rise to a nonuniform Bloch line. The vortex… CONTINUE READING
