Dielectric Properties of Rhombohedral

Table 2

Real part of dielectric constant ( ) and dielectric loss ( ) of PbNb2O6 in rhombohedral phase, PNS sample, for different frequencies at two different temperatures for heating and cooling graphs. Here, and indicate the real part of dielectric constant at temperature 410°C and 575°C, respectively, and and indicate the dielectric loss values at 410°C and 575°C, respectively.
