Electrocaloric effect in KH₂PO₄ family crystals
The proton ordering model for the KH₂PO₄ type ferroelectrics is modified by taking into account the dependence of the effective dipole moments on the proton ordering parameter. Within the four-particle cluster approximation we calculate the crystal polarization and explore the electrocaloric effect...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The proton ordering model for the KH₂PO₄ type ferroelectrics is modified by taking into account the dependence of the effective dipole moments on the proton ordering parameter. Within the four-particle cluster approximation we calculate the crystal polarization and explore the electrocaloric effect. Smearing of the ferroelectric phase transition by a longitudinal electric field is described. A good agreement with experiment is
obtained. |
