Bismuth zinc niobate pyrochlore, a relaxor-like non-ferroelectric
Rozana Aina, Maulat Osman, Dr.; Masó, Nahum; West, Anthony R. (The American Ceramic Society, 2012-01)Fixed frequency plots of ε and tan δ versus temperature for (Bi 1.5Zn 0.5)(Zn 0.5Nb 1.5)O 7 (BZN) ceramics with the pyrochlore structure show relaxor-like response below ∼180 K with frequency-independent permittivity of ... -

Mohd Sobri, Idris, Dr.; Rozana Aina, Maulat Osman, Dr. (Trans Tech Publications, 2013)The effect of preparation conditions, temperature and atmosphere, on oxygen stoichiometry and interlayer cation mixing in the layered rock salt material LiNi0.8Mn0.1Co0.1O2-δ has been investigated using X-Ray powder ... -
Ferroelectric and relaxor ferroelectric to paralectric transition based on Lead Magnesium Niobate (PMN) materials
Rozana Aina, Maulat Osman, Dr.; Mohd Sobri, Idris, Dr.; Zul Azhar, Zahid Jamal, Dato Prof. Dr.; Sanna, Taking, Dr.; Syarifah Norfaezah, Sabki, Dr.; Poopalan, Prabakaran, Dr.; Mohd Natashah, Norizan; Ili Salwani, Mohamad (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 ... -
Structure refinement strategy of Li-based complex oxides using GSAS-EXPGUI software package
Mohd Sobri, Idris, Dr.; Rozana Aina, Maulat Osman, Dr. (Trans Tech Publications, 2013)This paper discussed refinement strategy that been used to reveal crystallographic properties of lithium-based complex oxides with layered rock salt structure. Rietveld analysis using XRD data was used to determine the ...
