Dysonian line in the electron spin resonance of highly conductive cuin2s4 single crystals

Abstract

Electron spin resonance (ESR) spectra have been measured in CdIn2S4 single crystals with various resistivities (ρ= 106- 10-3 Ω.cm). As the conductivity increases, samples vary from insulator-like semiconductors to degenerate ones. ESi spectra due to donor electrons are observed under illumination in high resistive samples, whereas Dysonian lines appeal in low resistive ones. From the line shape analysis, we conclude that the variation in ESR line shapes with the concentra tion of donors arises from the motion of electrons in the paramagnetic centers. © 1993 The Japan Society of Applied Physics.
