Microfabricated Atomic Magnetometers and Applications



John E. Kitching, Svenja A. Knappe, Vishal Shah, P Schwindt, William C. Griffith, Ricardo Jimenez Martinez, Jan Preusser


We describe recent work at NIST to develop compact, sensitive atomic magnetometers using a combination of precision optical spectroscopy, atomic physics and techniques of micro-electro-mechanical systems (MEMS). These instruments have sensor head volumes in the range of a few mm3 but are capable of sensing magnetic fields of a few pT/√Hz in a shielded, low-field environment. We discuss design, fabrication and testing of several of these devices and propose several applications for which such instruments might be of use.
