摘要
An object wave made of an electron beam influenced by a sample and reference beam made of an electron beam not influenced by the sample are made to interfere with each other where a magnetic field has been applied to the sample to create a first electron-beam hologram and create a first reconstructed phase image from the first electron-beam hologram. An object wave made of an electron beam influenced by the sample and a reference beam made of an electron beam not influenced by the sample are made to interfere where a magnetic field has not been applied to the sample to create a second electron-beam hologram and create a second reconstructed phase image from the second electron-beam hologram. Magnetic field information indicating the influence of the magnetic field on the sample is acquired on the basis of the difference between the first and second reconstructed phase images.
