Abstract

Radiation damping (RD) is a combined manifestation of the nuclear spins and the resonant circuit. Particularly for intense nuclear magnetic resonance (NMR) signals, the coupling of the magnetization with the circuit of the radiofrequency coil induces a current in the receiver coil to generate a rotating magnetic field and thus producing a torque on the magnetization to return transverse magnetization back to equilibrium much faster than relaxation processes. RD is an important phenomenon as high magnetic field spectrometers are often used in combination with probes with high quality factors, such as probes with cryogenically cooled detection coils. This article provides a comprehensive overview of the phenomenon of RD.
