摘要：
This work examines conditions for skyrmion lattice stability in BiFeO3 multiferroic films possessing record high ferroelectric and antiferromagnetic transition temperatures, giant polarization, and a giant magnetoelectric effect. Using analytical and numerical calculations, we demonstrate stability of solitary spin vortices (skyrmions) and skyrmion lattices in BiFeO3 films owing to the Dzyaloshinskii-Moriya interaction. Our results confirm that BiFeO3 can be used as a matrix for chips with ultrahigh data density, up to 10 Tb/cm(2).
