Imaging damage in steel using a diamond magnetometer
L. Q. Zhou, R. L. Patel, A. C. Frangeskou +6
We demonstrate a simple, robust and contactless method for non-destructive testing of magnetic materials such as steel. This uses a fiber-coupled magnetic sensor based on nitrogen…
Sub-nanotesla magnetometry with a fibre-coupled diamond sensor
R. L. Patel, L. Q. Zhou, A. C. Frangeskou +12
Sensing small magnetic fields is relevant for many applications ranging from geology to medical diagnosis. We present a fiber-coupled diamond magnetometer with a sensitivity of (31…
Decoration of growth sector boundaries with single nitrogen vacancy centres in as-grown single crystal HPHT synthetic diamond
Philip L. Diggle, Ulrika F. S. D'Haenens-Johansson, Ben L. Green +5
Large (> 100 mm), relatively pure (type II) and low birefringence single crystal diamond can be produced by high pressure high temperature (HPHT) synthesis. In this study we ex…
Doubly-charged silicon vacancy center, photochromism, and Si-N complexes in co-doped diamond
B G Breeze, C J Meara, X X Wu +13
We report the first experimental observation of a doubly-charged defect in diamond, SiV2-, in silicon and nitrogen co-doped samples. We measure spectroscopic signatures we attribut…
