摘要：
A scanning magnetism detector includes a probe made of a solid material formed of a single crystal having spin polarization and electrical conductivity properties. When the probe is brought into proximity with a magnetic substance, a surface condition of the magnetic substance can be detected by measuring tunnel current flow between the probe and the surface of the magnetic substance.
