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.

A method for determining the magnetic characteristics of a body, comprising:
- generating a beam of particles, which particles undergo a known charge state change in response to an exchange of 2 electrons having predetermined magnetic moments;
- focusing said beam on said body such that said beam is reflected from the surface of said body;
- and
- measuring the number of particle charge state changes which occurred as a result of an exchange of 2 electrons in said reflected beam, as an indication of the magnetic value of the body.
Apparatus for determining the magnetic characteristics of a body, comprising:
- means for generating a beam of particles, which particles undergo a known ionization state change in response to an exchange of two electrons having predetermined angular moments;
- means for focusing said beam on said body such that said beam is reflected from the subface of said body;
- and
- means for measuring the number of particle ionization state changes which occurred as a result of an exchange of 2 electrons in said reflected beam, as an indication of the magnetic value of the body.
