  • Method and apparatus for detecting magnetism by means of electron spin polarization measurements through dielectronic transition
    Patent number: 4455486
    Abstract: A beam of particles which undergoes a known charge state change in response to an exchange of two electrons having preoriented moments is generated. The beam is focused on a body, the magnetic properties of which are to be determined, in such a manner that the beam is reflected from the surface of the body. The number of particle charge state changes which occurred are measured in the reflected beam and provide an indication of the square of the magnetic value of the body and shows the magnetic state of the surface of the body.
