Dataset for the article "Microwave-free imaging magnetometry with nitrogen-vacancy centers in nanodiamonds at near-zero field"

This repository contains the dataset obtained from a wide-field, microwave-free imaging magnetometer utilizing NV centers in nanodiamonds by exploiting the cross-relaxation feature near zero magnetic fields under ambient conditions without applying microwaves. The data was taken between October 2023 and March 2024. Please consult the README.md file for further information. We recommend you read the article (arXiv:2409.02199) for more information on the data analysis methods and results.
