Electron paramagnetic resonance (EPR) which is the absorption of electromagnetic waves in the microwave frequency domain has been used for many years to study magnetic dipoles in crystals subjected to magnetic fields. These magnetic dipoles arise fro

We have used electron paramagnetic resonance to study the migration of photoproduced self-trapped holes (STH's) at temperatures below 30 K, where the migration can no longer proceed by classical phonon-assisted hopping, and a tunneling mechanism domi

Hole-trapping at cation vacancies and iodide impurity in silver halides was studied by means of electron paramagnetic resonance (EPR). In AgCl, the hole was found to be preferentially self-trapped on a Ag ion next to a cation vacancy, forming a pertu

Investigation of polycrystalline diamond films by electron paramagnetic resonance at 9.5 and 35 GHZ has revealed the presence of forbidden transitions resulting from a simultaneous microwave induced flipping of unpaired electron spins and environment

We report the first observation of an energy barrier in the transition of a metastable free hole to the self-trapped state. The lifetime of the free hole was monitored by using electron paramagnetic resonance to measure the competition between self-t

Echo envelope modulation is calculated which includes quadrupole interaction of the nuclear spin. The strength of the quadrupole interaction must be smaller than the electron Zeeman interaction and the interaction between the electron spin and the ap

EPR studies on ultraviolet-irradiated crystals of AgCl: Pd have confirmed earlier results on AgCl: Cu for the existence of an energy barrier in the self-trapping of the photohole. The height of this barrier is near 1.8 meV. Migration of the self-trap
