Origin of the unusual dependence of Raman D band on excitation wavelength in graphite-like materials

A. K. Sood, Rajeev Gupta, S. A. Asher

We have revisited the still unresolved puzzle of the dispersion of the Raman disordered-induced D band as a function of laser excitation photon energy E $_{L}$ in graphite-like materi…

Raman Scattering in charge ordered Pr_{0.63}Ca_{0.37}MnO_{3} : Anomalous Temperature Dependence of Linewidth

Rajeev Gupta, G. Venketeswara Pai, A. K. Sood +2

We report the evolution of the Raman active A_g phonon modes in the charge-ordered manganite Pr_{0.63}Ca_{0.37}MnO_{3} as a function of temperature from 300K to 25K. Our studies re…
