Variation of Topology in Magnetic Bubbles in a Colossal Magnetoresistive Manganite

The emergence of zero-bias bubbles (≈100 nm in diameter) with various Bloch lines and their triangular lattice is revealed in a colossal magnetoresistive material, La1−xSrxMnO3, by means of Lorentz transmission electron microscopy (LTEM). The magnetization dynamics, and accompanying changes of the topological number of bubbles via the field-driven motion of the Bloch lines, are demonstrated by in situ LTEM observations.
