  • First Online:
High Sensitivity Magnetometers

Part of the book series: Smart Sensors, Measurement and Instrumentation ((SSMI,volume 19))

Abstract

Optical magnetometers (OPMs), implemented by optical interrogation of alkali-atoms contained in a vapor cell, are among the most sensitive detectors for magnetic fields. Due to the fact that weak magnetic fields are ubiquitous in our world, high-sensitive magnetometers are demanded in a wide range of scientific and practical applications. Here we review some of the highly miniaturized OPMs recently developed using silicon microfabrication techniques. This approach opens a number of attractive advantages, besides further miniaturization, such as integration of different sensing technologies within the same silicon platform and cost-efficient manufacturing of a large number of sensors with tight tolerances at potentially low cost.
