4 Jan 2023 | Abstract: | To investigate the caloric effects in the CsH$_2$PO$_4$ ferroelectric, a
modified pseudospin model of this crystal is used, which takes into account the
dependence of the parameters of interaction between pseudospins on lattice
strains. The model also takes into account the dependence of the effective
dipole moment of a pseudospin on the order parameter. In the two-particle
cluster approximation, the influence of the longitudinal electric field and
hydrostatic pressure on the molar entropy of the crystal was studied. The
electrocaloric and barocaloric effects were studied. The calculated
electrocaloric temperature change is about $1$ K; it can change its sign under
the influence of hydrostatic pressure. Barocaloric temperature change is about
$-0.5$ K; lattice anharmonicities were not taken into account in its
calculations. | Source: | arXiv, 2301.01544 | Services: | Forum | Review | PDF | Favorites |
