High Sensitivity Magnetometry with a Fibre-coupled Diamond Sensor
Abstract
The negatively charged nitrogen-vacancy (NV) centre in diamond is one of the most studied solid-state defects because it has spin states that can be initialised and detected optically at room temperature. A key technological development is the use of an ensemble of these defects for applications in high sensitivity magnetometry which may lead to the development of medical devices for techniques such as magnetocardiography. We present a fiber-coupled system which aims to detect the magnetic fields produced by electrical currents in the heart.
