Chlorine 35 nuclear quadrupole resonance (NQR) frequency and lineshape data, obtained with a Fourier transform magnetic resonance spectrometer, are presented for the antifluorite crystal K2ReCl6. In the temperature range investigated, 85 to 130 K, two structural phase transitions occur which reduce the crystal symmetry from cubic to tetragonal to monoclinic. The variation of the NQR spectrum with temperature and with hydrostatic pressure up to 2.64 kbar is documented. The structure of the spectrum and the intensity distribution within it are unexpected from previous studies of antifluorite systems. An explanation of the results is given which is based on recent discussions of nonlinear phenomena at phase transitions in crystals exhibiting reduced effective dimensionality.

In this work a study on the structural phase transitions of silicon undergone by two different methods were performed. The samples were submitted to high non-hydrostatic pressure applied by cyclic Vickers indentations and by the tool tip during the single point diamond turning. The indentations were performed on virgin surface (polished as received) and on an amorphous surface generated either by the machining process or RF sputtering. The analysis on the machined surface, debris on the diamond tool and around of imprints were also performed using Raman micro spectroscopy. The results indicated the formation of some phases may depend upon the initial structural state of the surface, i.e., amorphous or crystalline.
