Levitating charged ferromagnets in an electrodynamic trap

Under conditions where the total angular momentum of a ferromagnet is dominated by intrinsic spin, the ferromagnet will behave as a gyroscope. If such a ferromagnetic gyroscope can be sufficiently isolated from the environment, it can measure torques with a sensitivity beyond the spin-projection noise limit for independent particles. Levitation of a ferromagnetic particle by charging it and electrodynamically trapping it is a possible method for near frictionless suspension. We discuss experimental progress toward realizing a Levitating Ferromagnetic Gyroscope (LFG) with charged iron particles confined in a Paul trap.
