A method is for measuring phase currents of a device under test, in particular of an inverter, in which a sensor arrangement, which has a component including a crystal lattice with a defect, is arranged in a region of the device under test. The method includes using the sensor arrangement to detect a magnetic field formed by a vector of magnetic fields, the magnetic fields each in turn being brought about by one of the phase currents of the device under test, and calculating a vector of the phase currents from the vector of the magnetic fields based on a coefficient matrix.

Method for measuring phase currents of a device under test, in particular of an inverter

A method for ascertaining a change in a spatial orientation of a nuclear magnetic resonance (NMR) gyroscope having a diamond doped with color centers includes applying a static external magnetic field in a first direction, polarizing a nuclear spin of the color centers of the diamond in a direction of the static magnetic field, and generating a cophasal Larmor precession of the nuclear spin of the color centers of the diamond through application of an alternating magnetic field in a second direction perpendicular to the first direction, whose frequency corresponds to the Larmor frequency of the nuclear spin of the color centers. The method further includes measuring a phase of the Larmor precession, and ascertaining a change in the spatial orientation in a plane perpendicular to the first direction based on a deviation of the precession frequency from an expected value.
