Description
The axion provides a solution for the strong CP problem and is one of the leading
candidates for dark matter. In this talk, we propose an axion detection scheme based
on quantum nondemolition detection of magnons, i.e., quanta of collective spin
excitations in a ferromagnetic crystal. Furthermore, we give an upper limit on the
coupling constant between an axion and an electron for a certain mass of the axion
dark matter.
