A Microwave Study Of Charged Defects In Glasses

It is shown that charged defects in glasses give rise to cyclotron resonance under the combined effect of an electric and a magnetic microwave fields and a dc magnetic field. The effect is ascribed to the motion of paired electrons between charged defects. It has been investigated by studying signals radiated by the glasses by way of the induced electric polarisation oscillating at the second-harmonic frequency of the driving field.
