Dispersão dielétrica em materiais ferroelétricos.
(Universidade Federal de São Carlos, 2004-12-13)
In the last decades, the high frequency dielectric response has been one of
the most studied issues in the ferroelectricity area. The main dielectric
characteristic is the strong dependence of the dielectric parameters ...
Estudo das transições de fase em cerâmicas ferroelétricas de PZT e PLZT através de espectroscopia mecânica
(Universidade Federal de São Carlos, 2008-10-08)
Lead titanate zirconate (PZT) and lanthanum-modified lead titanate zirconate (PLZT) ferroelectric ceramics have been great scientific and technologic interest, due to the possibility
of your physics properties can be ...
Regras de ocupação e influência de dopantes trivalentes em matrizes cerâmicas transparentes de PLZT 9/65/35
(Universidade Federal de São Carlos, 2009-10-01)
In this work, were investigated the occupancy of rare-earth ions in lattice site of the ferroelectric system (Pb,La)(Zr,Ti)O3, or PLZT. The influence on the structural, microestructural, dielectric, ferroelectric, optical ...
