Abstract

Electrically detected magnetic resonance (EDMR) spectroscopy is the observation of electron magnetic resonance through detection of conductivity effects of electron spin states in condensed matter systems. Over the past 15 years, this technique has undergone a dramatic shift from a continuous-wave, adiabatic magnetic field sweep experiment that was developed in the 1960s to a pulse spectroscopy technique, which allows for a range of pulse sequences nearly as broad and versatile as that for pulse electron paramagnetic resonance spectroscopy. Here, the underlying physical mechanisms that are used for EDMR spectroscopy and experimental techniques are outlined, and current developments are discussed. These include the development of specialized pulse EDMR techniques and expansion of EDMR spectroscopy to a wider spectrum of spectrometer frequencies and magnetic fields, ranging from sub-millitesla to high field (>10 T).
