Optical Detection of Magnetic Resonance

Abstract

Abstract. The combination of magnetic resonance with laser spectroscopy provides some interesting options for increasing the sensitivity and information content of magnetic resonance. This review covers the basic physics behind the relevant processes, such as angular momentum conservation during absorption and emission. This can be used to enhance the polarization of the spin system by orders of magnitude compared to thermal polarisation as well as for detection with sensitivities down to the level of individual spins. These fundamental principles have been used in many different fields. This review summarises some of the examples in different physical systems, including atomic and molecular systems, dielectric solids composed of rare earth and transition metal ions and semiconductors.

Level-crossing induced spin phenomena in SiC: A theoretical study

“…Defect color centers are promising objects for various applications, such as optical detection of magnetic resonance [1][2][3], quantum information processing [4,5], nanosensing [6][7][8][9][10][11] and nuclear spin hyperpolarization [12][13][14][15][16][17]. An example of a particularly well studied and widely used system of this kind is given by the negatively charged nitrogen-vacancy centers, NVcenters, in diamond crystals [1,2].…”
