Laser threshold magnetometry [PDF]
New Journal of Physics, 2016 We propose a new type of sensor, which uses diamond containing the optically active nitrogen-vacancy (NV ^− ) centres as a laser medium. The magnetometer can be operated at room-temperature and generates light that can be readily fibre coupled, thereby ...

Ultrasensitive Optomechanical Magnetometry [PDF]
Advanced Materials, 2014 A cavity optomechanical magneto-meter operating in the 100 pT range is reported. The device operates at earth field, achieves tens of megahertz bandwidth with 60 μm spatial resolution and microwatt optical-power requirements. These unique capabilities may have a broad range of applications including cryogen-free and microfluidic magnetic resonance ...

Composite-pulse magnetometry with a solid-state quantum sensor [PDF]
, 2012 The sensitivity of quantum magnetometers is challenged by control errors and, especially in the solid-state, by their short coherence times. Refocusing techniques can overcome these limitations and improve the sensitivity to periodic fields, but they ...
