| 英文摘要 | The polarized neutron imaging technique provides a non-invasive method of characterizing localized magnetic fields inside superconductors. however, complete understanding of the magnetic field distribution has yet to be realized experimentally due to the complexity of the interaction between neutron polarization and magnetic field. in this article, we show that a well-defined and controlled magnetic field through the neutron path contributes to simplify the data analysis and makes future quantitative polarized neutron imaging possible. this is demonstrated in a set of experiments that visualize the magnetic field distribution inside and around the superconductors. the experimental results demonstrate that proper guide field setup allows the visualization of the magnetic field expulsion at the surface of the superconductor in the zero-field cooling condition, as well as the magnetic field trapped inside the superconductor under field cooling condition. published under license by aip publishing. |
