Electron Paramagnetic Resonance - an overview

We address electron spin resonance of single magnetic moments in a tunnel junction using time-dependent electric fields and spin-polarized current. We show that the tunneling current directly depends on the local magnetic moment and that the frequency of the external electric field mixes with the characteristic Larmor frequency of the local spin. The importance of the spin-polarized current.

Applications of electron paramagnetic resonance

Electron Paramagnetic Resonance (EPR) What is EPR? EPR is a spectroscopic technique that detects chemical species that have unpaired electrons. A great number of materials contain such paramagnetic entities, which may occur either as electrons in unfilled conduction bands, electrons trapped in radiation damaged sites, or as free radicals, various transition ions, bi-radicals, triplet states.

Electron paramagnetic resonance was first discovered by former Soviet physicist E.K. Zavois based on paramagnetic salts such as MnCl2 and CuCl2 in 1944. Physicists originally used this technique to study the electronic structures, crystal structures, dipole moments, and molecular structures of certain complex atoms. Later, based on the results of electron paramagnetic resonance measurements.
