Axion Dark Matter Detection using an LC Circuit
arXiv:1310.8545 · doi:10.1103/PhysRevLett.112.131301
Abstract
It is shown that dark matter axions cause an oscillating electric current to flow along magnetic field lines. The oscillating current induced in a strong magnetic field $\vec{B}_0$ produces a small magnetic field $\vec{B}_a$. We propose to amplify and detect $\vec{B}_a$ using a cooled LC circuit and a very sensitive magnetometer. This appears to be a suitable approach to searching for axion dark matter in the $10^{-7}$ to $10^{-9}$ eV mass range.
