High dynamic-range and portable magnetometer using ensemble nitrogen-vacancy centers in diamond
Himanshu Kumar, Dasika Shishir, Maheshwar Mangat +2
Nitrogen vacancy (NV) centers in diamonds have been explored for realizing a wide range of sensing applications in the last decade due to their unique quantum properties. Here we r…
