Raman spectra of finely polished pellets of
cathod ematerial have been recorded using HORIBA Jobin Yvon (HR 800)
Raman spectrometer. Temperature dependent electrical resistivity
measurementswere done on the palletized cathode material using linear
four probe technique. The sampleswere cooled to 100 K and then heated
to room temperature using a small resistive heater connected to the edge
