electron spin echo

electron spin echo

[i‚lek‚trän ′spin ‚ek·ō]
(solid-state physics)
A net magnetization of a material that is sometimes observed at a particular time following the application of two or more short, intense pulses of microwave radiation; in the simplest case, two pulses separated by a time interval t are followed by a net magnetization at time t ′ after the second pulse.

Electron spin echo (ESE) EPR spectra were recorded by means of field-swept two-pulse echo sequence [pi]/2-[tau]-[pi] with the pulse length of [pi] pulse of 12 ns and time delay r = 240 ns.
The dependence of the kinetics of electron spin echo amplitude decay on increase of delay time between the microwave pulses is presented in Figure 3.
Since the discovery of EPR in 1944, further refinements in the technique have led to variations such as pulse EPR, electron nuclear double resonance (ENDOR) and electron spin echo envelope modulation (ESEEM) spectroscopy.
