Description
For many spin-dependent dark matter-electron couplings, the DM's scattering rate in a target material can be written in terms of its dynamical magnetic susceptibility. This quantity can be inferred from neutron scattering data, without requiring a microscopic model of the material. As a proof of principle, I will show that an existing dataset can be used to find the DM scattering rate in yttrium iron garnet.
