Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 13/04/2023)Optical control of ferroelectric properties have been attracted a growing interest as an alternative to the conventional control by applied electric fields. However, the major drawback for achieving an effective reversible ... -
Visualização de estrutura de domínios em cerâmicas e nanoestruturas ferroelétricas via microscopia de piezoresposta
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 27/02/2013)In this work, the domain structure of a transparent ferroelectric ceramic of (Pb0,79La0,21)TiO3 (PLT 21) was investigated in detail by piezoresponse force microscopu (PFM) and a protocol of measurements and analysis of the ... -
Ondas de spin em paredes de domínio unidimensionais em monocamadas magnéticas
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 16/08/2012)Recent investigations on ferromagnetic monolayers predict the existence of spinwave modes without gap in the spectrum, even in the presence of anisotropy. These excitations propagate within the domain walls that exist in ...
