Bartington Instruments can reveal that it is supporting research by the University of Warwick into diamond technology, which promises miniaturization of magnetometers, making possible significant developments in high spatial resolution magnetocardiography (MCG) systems.
This new technology makes use of a long-known but difficult to exploit characteristic of diamonds with nitrogen-vacancy (NV) centres at molecular level. These NV centres emit red florescence which can be used to detect their magnetic resonance– essentially functioning as a magnetometer.
The research team led by Gavin Morley has already constructed a fibre-based NV magnetometer, in an unshielded environment and with no noise subtraction. Current developments are expected to demonstrate further advances toward our goal of developing commercially viable diamond NV magnetometers. The new project has funding from the EPSRC’s UK Quantum Technology Programme via the NQIT (Networked Quantum Information Technologies, www.nqit.co.uk) Hub.
