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 ... -
Influence of mechanical alloying on dielectric features of ferroelectric BaTio₃ microcrystals
(ESG, 2014)Dielectric features of BaTiO₃ microcrystals made by mechanical alloying method in the ball mill of SPEX 8000 are studied. Temperature and hysteresis loops are investigated and Curie temperature as well as dielectric constant ...
