Data for Subnanotesla magnetometry with a fiber-coupled diamond sensor
Listed in figshare
Sensing small magnetic fields is relevant for many applications ranging from geology to medical diagnosis.
Description
We present a fiber-coupled diamond magnetometer with a sensitivity of (310 ± 20) pT/Hz‾‾‾√ in the frequency range of 10-150 Hz. This is based on optically detected magnetic resonance of an ensemble of nitrogen vacancy centers in diamond at room temperature.
Fiber coupling means the sensor can be conveniently brought within 2 mm of the object under study.<br><br>Data record consists of a single zip archive containing the raw data, organised into subfolders according to data type, and raw text files describing the data types. The ODMR data included are .csv/.mat files taken from a Picoscope oscilloscope. The sensitivity files are the fast Fourier transforms of the voltage traces when monitoring a resonance for 1 second.

The files are .csv/.mat and are on-resonance (magnetically sensitive), off-resonance (not magnetically sensitive) and electronic noise (laser and microwaves are switched off).
