XRD patterns of five W substituted samples (, , 0.25, 0.75, 1.0, and 1.4) at room temperature. Insert: enlargement of the diffraction patterns of (123) reflection.
The curves of internal friction vs temperature for five different samples (, 0.25, 0.75, 1.0, and 1.4) at a frequency of . For the relative modulus, only the curve for the sample is given for clarity.
The variation of internal friction and relative modulus vs temperature for a sample at four different measurement frequencies of 0.5, 1.0, 2.0, and , respectively, where the data at 0.5, 1.0, and are presented with lines for clarity.
The conductivity curve vs reciprocal of temperature for a sample and its fitting by using the Arrhenius model at lower temperature and the VTF model at higher temperature.
