High-sensitivity diamond magnetometer with nanoscale resolution Academic Article uri icon


  • The detection of weak magnetic fields with high spatial resolution is an important problem in diverse areas ranging from fundamental physics and material science to data storage and biomedical science. Here, we explore a novel approach to the detection of weak magnetic fields that takes advantage of recently developed techniques for the coherent control of solid-state electron spin quantum bits. Specifically, we investigate a magnetic sensor based on nitrogen-vacancy centres in room-temperature diamond. We discuss two important applications of this technique: a nanoscale magnetometer that could potentially detect precession of single nuclear spins and an optical magnetic-field imager combining spatial resolution ranging from micrometres to millimetres with a sensitivity approaching a few fTHz 1/2 . 2008 Macmillan Publishers Limited.
