Influence of charged walls and defects on DC resistivity and dielectric relaxation in Cu-Cl boracite
C. Cochard, T. Granzow, C. M. Fernandez-Posada +5
Charged domain walls form spontaneously in Cu-Cl boracite on cooling through the phase transition. These walls exhibit changed conductivity compared to the bulk and motion consiste…
Asymmetric electrocaloric effects in PbSc0.5Ta0.5O3 on field application and removal
E. Stern-Taulats, P. Lloveras, M. Barrio +6
Electrically driven thermal changes in PbSc0.5Ta0.5O3 bulk ceramics are investigated using temperature and electric-field dependent differential scanning calorimetry and infrared t…
Quasi-indirect measurement of electrocaloric temperature change in PbSc0.5Ta0.5O3 via comparison of adiabatic and isothermal electrical polarization data
S. Crossley, R. W. Whatmore, N. D. Mathur +1
Electrically driven adiabatic changes of temperature are identified in the archetypal electrocaloric material PbSc0.5Ta0.5O3 by comparing isothermal changes of electrical polarizat…
Electrocaloric cooling cycles in lead scandium tantalate with true regeneration via field variation
S. Crossley, B. Nair, R. W. Whatmore +2
There is growing interest in heat pumps based on materials that show thermal changes when phase transitions are driven by changes of electric, magnetic or stress field. Importantly…
No clear evidence of ferroelectric order in tensile-strained anatase-TiO2 thin films grown on (110) NdGaO3 substrates
Stella Skiadopoulou, Stanislav Kamba, Jan Drahokoupil +4
Very recently there was a report of the discovery using piezoelectric force microscopy (PFM) of a switchable ferroelectric polarization in 1.6 % tensile strained TiO2 thin film wit…
Giant electrocaloric effect in the thin film relaxor ferroelectric 0.9 PbMg_(1/3)Nb_(2/3)O_3 - 0.1 PbTiO_3 near room temperature
A. S. Mischenko, Q. Zhang, R. W. Whatmore +1
We have recently observed a giant electrocaloric effect (12 K in 25 V) in 350 nm sol-gel Pb Zr_0.95 Ti_0.05 O_3 films near the ferroelectric Curie temperature of 242oC. Here we dem…
Giant electrocaloric effect in thin film Pb Zr_0.95 Ti_0.05 O_3
A. Mischenko, Q. Zhang, J. F. Scott +2
An applied electric field can reversibly change the temperature of an electrocaloric material under adiabatic conditions, and the effect is strongest near phase transitions. This p…
