The electrocaloric response in Lanthanum-modified lead zirconate titanate ceramic
B. Asbani, J. -L. Dellis, A. Lahmar +7
Over the past decades, there has been significant interest in new cooling technology based on the electrocaloric effect. The large electrocaloric effect observed in polymeric and i…
Electrocaloric response in Lanthanum-modified lead zirconate titanate ceramics
B. Asbani, M. El Marssi, J. -L. Dellis +8
Recent findings of a large electrocaloric (EC) effect in polymeric and inorganic ferroelectric materials open a potential possibility of development of solid-state cooling or heati…
Magnetic control of large room-temperature polarization
Ashok Kumar, G. L. Sharma, R. S. Katiyar R. Pirc +1
Numerous authors have referred to room-temperature magnetic switching of large electric polarizations as The Holy Grail of magnetoelectricity.We report this long-sought effect usin…
Vogel-Fulcher freezing in relaxor ferroelectrics
R. Pirc, R. Blinc
A physical mechanism for the freezing of polar nanoregions (PNRs) in relaxor ferroelectrics is presented. Assuming that the activation energy for the reorientation of a cluster of…
Hybrid soft-mode and off-center Ti model of barium titanate
R. Pirc, R. Blinc
It has been recently established by NMR techniques that in the high temperature cubic phase of BaTiO the Ti ions are not confined to the high symmetry cubic sites, but rather o…
Dynamics of relaxor ferroelectrics
R. Pirc, R. Blinc, V. Bobnar
We study a dynamic model of relaxor ferroelectrics based on the spherical random-bond---random-field model and the Langevin equations of motion. The solution to these equations is…
