    Study of the Raman Active Modes for the Suzuki Phase in Doped Alkali Halides

    Raman spectroscopy is shown to be an appropriate tool to characterise the Suzuki phase of doped alkali halides. Good agreement is found between our experimental data for 6NaCl:MnCl2, 6NaCl:CdCl2 and 6NaCl:MgCl2 a...
