| Outline of Final Research Achievements |
In this study, we have developed a high-resolution subsurface magnetic field imaging system capable of visualizing electric current distribution in a distance from the measurement area. This system equips a tunneling magnetoresistance device as a magnetic field sensor and a scanning device with nanometer-scale precision. Additionally, This system have a imaging software based on integral geometry electromagnetic field reconstruction theory capable of achieving a spatial resolution equal to minimum size of a magnetic field sensor for a higher-spatial resolution image. We have succeeded in imaging electric current distributions at metal-metal junction interface, LED chips, rechargeable batteries and so on using this system.
