Outlining origin of diffuse plus relaxor ferro- to para-electric phase transition in lead metaniobate-based materials

Lead metaniobate-based ferroelectrics were studied in terms of thermal spectra of dielectric permittivity, Curie-Weiss law and hysteresis loop characteristics. This work shows that while dopants are able to promote a change of the ferro- to para-electric phase transition appearance from normal to diffuse, transformation to a diffuse plus relaxor transition… (More)
