Electrical properties of fresnoite Ba2TiSi2O8 using impedance spectroscopy
(Trans Tech Publications, 2013)
Fresnoite with composition Ba2TiSi2O8 (B2TS2) was first found in 1965, adopting a non-centrosymmetric structure. It also reported to crystallize in a tetragonal unit cell with a=8.52Å and c=5.210Å leading to some possible ...
Ferroelectric and relaxor ferroelectric to paralectric transition based on Lead Magnesium Niobate (PMN) materials
(Trans Tech Publications, 2013)
First ferroelectric materials were found in Rochelle salt was in a perovskite structure. Lead Magnesium Niobate (PMN) is a perovskites with a formula of PbMg1/3Nb2/3O3 (PMN) and are typical representatives for most of all ...
