摘要：

We have observed the response of spin arrangements to external magnetic fields in a multiorbital Mott insulator, ferromagnetic insulating manganite La7/8Sr1/8MnO3, by low-temperature in situ Lorentz microscopy. Magnetic fields normal to the plane of the thin-plate sample continuously change the width of domains in the serpentine-like domain structure, eventually giving rise to nanoscale elliptical magnetic bubbles of similar to 200 nm major diameter at 3.6 kOe. The formation of these bubbles implies large magnetic anisotropy related to the orbital ordering and suggests the possibility of manipulating the bubbles using an electric field.
