Self-poling with oxygen off-stoichiometry in ferroelectric hexagonal manganites

Topological vortices with complex domains and domain walls exist in hexagonal manganites, which undergo a structural transition accompanying ferroelectric polarization and trimerization. We have systematically studied the origin of two different types (type-I and type-II) of vortex domains with cont...
