Ferroelectric materials

Relaxor ferroelectric

Relaxor ferroelectrics are ferroelectric materials that exhibit high electrostriction. As of 2015, although they have been studied for over fifty years, the mechanism for this effect is still not completely understood, and is the subject of continuing research. Examples of relaxor ferroelectrics include: * lead magnesium niobate (PMN) * (PMN-PT) * (PLZT) * (PSN) * Barium Titanium-Bismuth Zinc Niobium Tantalum (BT-BZNT) * Barium Titanium-Barium Strontium Titanium (BT-BST) (Wikipedia).

Ferroelectrics and Piezoelectrics

Why is it that titanates and zirconates can achieve such remarkably large dielectric constants? These perovskites have ions that can move substantially as the structure switches from cubic to tetragonal. The transition occurs at the Curie Temperature above which there is no net polarizatio

AWESOME SUPERCONDUCTOR LEVITATION!!!

A quantum levitator it's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics. The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of fo
