摘要：
The anisotropic magnetic domain structure of a layered manganite La1.4Sr1.6Mn2O7 has been analyzed quantitatively. The evaluated dimensions of the domain indicate the low dimensionality and reproduce spontaneous formation of the bubble domain taking stability of the bubble domain into account. The ferromagnetic regions observed below the Neel temperature might be responsible for the limited tunneling magnetoresistance ratio reported in this compound. (C) 2001 American Institute of Physics.
