Role of charge compensation mechanism on phase formation, dielectric and ferroelectric properties in aliovalent Gd3+ ion modified PbMg1/3Nb2/3O3 ceramics
Adityanarayan H. Pandey, Surya Mohan Gupta
Phase, microstructural, dielectric and ferroelectric properties investigation clearly reveal that the charge imbalance created due to alio-valent Gd3+-ion substitution at Pb2+ site…
Investigation of re-entrant relaxor behaviour in lead cobalt niobate ceramic
Adityanarayan H. Pandey, Surya Mohan Gupta
The temperature dependent dielectric properties revealed re-entrant relaxor behaviour (Tm ~130 K and 210 K for 1 kHz) below a high temperature diffused phase transition, Tc ~270 K…
Microstructural, vibrational, dielectric and ferroelectric properties correlation in hot-pressed PbMg1/3Nb2/3O3 ceramics
Adityanarayan H. Pandey, Surya M. Gupta, Vasant G. Sathe +1
Microstrctural, vibrational, ferroelectric and dielectric properties investigation reveals non-stoichiometric chemical ordered regions (CORs) and relaxor like dielectric characteri…
Bipolar electrocaloric effect in Pb1-xGdx(Mg1+x/3Nb2-x/3)O3 ceramic: relaxor with super-dipolar glass state
Adityanarayan H. Pandey, A. M. Awasthi, Surya Mohan Gupta
The electrocaloric (EC) effect is calculated for Gd-substituted PMN (x = 0 to 0.1) relaxors from temperature dependent heat capacity and polarization measurements, using a thermody…
