英文摘要
Electron holography and Lorentz microscopy were used to clarify the features of "super-ferromagnetism" that is formed in a self-assembled film of magnetic nanoparticles. The electron holography revealed that the micron-scale super-ferromagnetic domain structures moved as the sample temperature increased. Also the holography successfully showed the transition of super-ferromagnetism to super-paramagnetism. The Lorentz microscopy clarified that the magnetic moments in 100 - 300 nm region rapidly rotated because of the thermal energy.
