Abstract

The disclosure relates to a method for measuring a current using a diamond material. The diamond material has at least one nitrogen deposit and an imperfection in a crystal lattice of the diamond material, adjacent to the nitrogen deposit. The method comprises a providing step, a detecting step and an evaluating step. In the providing step, electromagnetic waves are provided to excite the diamond material. In the evaluating step, an intensity of a fluorescence of the diamond material is detected. In the evaluating step, the intensity and a frequency of the electromagnetic waves are evaluated in order to determine a magnetic field strength influencing the fluorescence.
