  • Investigation of electrocaloric effect in PMN-PT relaxor thin films 
    Correia, T. M.; Young, J. S.; Whatmore, Roger W.; Scott, J. F.; Nathur, N. D.; Zhang, Qi (American Institute of Physics, 2009-12-31)
    Permittivity measurements of a 0.93PMN-0.07PT thin film show a broad maximum near 35 ºC, and an anomaly at the depolarizing temperature Td = 18 ºC on heating only, suggesting a dipolar glass-relaxor phase transition. No ...
  • 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 ...
  • 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 ...
