“…With an increase in Li + /W 6+ content, the dielectric peaks show broadening and the temperature of the maximum ε r ( T m ) shows a clear shift with frequency, suggesting a diffuse phase transition. To characterize the degree of diffusion of the BSPT–LW x ceramics, the modified Curie–Weiss relationship, and the parameters of Δ T m and Δ T dif were applied
2 . As shown in Equations ():
where C is the Curie–Weiss constant and γ the is diffusion coefficient.…”
