摘要：

The ferroelectric-antiferromagnet BiFeO3 shows long period modulated magnetic structure with lambda = 620 Angstrom. The origin of this spatially modulated structure can be explained in terms of existence of relativistic Lifshitz invariants. By minimizing the free energy of the crystal and taking the Lifshitz invariants into account the spatially modulated spin structure (SMSS) is described.
