Ferroelectric Domain Structure of La-modified Lead Titanate Ceramics
14 Dec 2018 | Presentation Materials | Contributor(s): Brian Demczyk, G. Thomas
Presentation describes the ferroelectric domain structure of Lanthanum-modified lead titanate ceramics, as deduced by transmission electron microscopy, including the ferroelectric to paraelectric phase transformation. A significant result was the observation of a minimum grain size for...
Magnetic Domain Reversal
07 May 2018 | Animations | Contributor(s): Brian Demczyk
Videos show magnetic domain disappearance and reappearance in a Co-22% Ct thin film when heated/cooled through the Curie Point.
Ferroelectric Domain Motion
Videos show total ferroelectric domain disappearance in bulk La-doped lead titanate, and incomplete reversal in a small (< 0.5 micrometer) grain, when heated through the Curie point.
