  • Investigation of the electrocaloric effect in a PbMg2/3Nb1/3O3-PbTiO3 relaxor thin film 
    Correia, T. M.; Young, J. S.; Whatmore, Roger W.; Scott, J. F.; Mathur, N. D.; Zhang, Qi (American Institute of Physics, 2009-05)
    Permittivity measurements of a 0.93PMN-0.07PT thin film show a broad maximum near 35 °C, and an anomaly at the depolarizing temperature Td = 18 °C on heating only, suggesting a dipolar glass-relaxor phase transition. No ...
  • Nanocoatings on micro- or nano-particles 
    Libor, Zsuzsanna; Zhang, Qi; Israel, C.; Mathur, N. D. (Maney Publishing, 2009-11)
    In recent years, coating processes with nanoparticles have been investigated for the development of nanostructured materials. In this work we report the core-shell structures of micro-composites of SiO2/Ni, SiO2/Fe3O4, and ...
  • PST thin films for electrocaloric coolers 
    Correia, T. M.; Kar-Narayan, S.; Young, J. S.; Scott, J. F.; Mathur, N. D.; Whatmore, Roger W.; Zhang, Qi (Iop Publishing Ltd, 2011-04-07)
    Relaxor behaviour in a thin film of partially ordered PbSc0.5Ta0.5O3 (PST) was confirmed via slim P-E loops and the frequency dependence of the temperature at which the dielectric constant is maximum. Indirect measurements ...
