While seminal characterizations by volume sensitive neutron diffraction led to think that only one cycloidal propagation was chosen in a BiFeO3 single crystal, NV magnetometry imaging reveal several possible cycloidal propagation sat the surface, forming antiferromagnetic domains at the microscopic scale. Eventually, antiferromagnetic topological defects are also observed in this very rich lamellar pattern and might be promising candidates as information storing entities for future ultrafast electronics.
