报告摘要:
The dynamics of a single-domain magnetic needle, which can be used as a high precision magnetometer, are analyzed. The uncertainty of the magnetometer due to Gilbert dissipation and the associated internal B field fluctuations is determined. We also consider needle dynamics in an inhomogeneous magnetic field (e.g., a Ioffe-Pritchard trap) and discuss magnetic levitation, and treat external noise effects.
