Large electrocaloric strength in ferroelectric nematic liquid crystals with a tuneable operational temperature range
Diana I. Nikolova, Rachel Tuffin, Mengfan Guo +5
The electrocaloric (EC) effect offers a promising energy-efficient and clean cooling technology. We present the first direct measurements of EC temperature change in a new family o…
Large magnetoelectric coupling in multiferroic oxide heterostructures assembled via epitaxial lift-off
David Pesquera, Ekaterina Khestanova, Massimo Ghidini +12
The strain dependent functional properties of epitaxial transition metal oxide films can be significantly modified via substrate selection. However, large lattice mismatches preclu…
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…
Absence of charge-density-wave sliding in epitaxial charge-ordered Pr0.48Ca0.52MnO3 films
B. Fisher, J. Genossar, L. Patlagan +5
For an epitaxial Pr0.48Ca0.52MnO3 film on NdGaO3, we use transmission electron microscopy to observe a "charge-ordered" superlattice along the in-plane direction a. The same film s…
Nanoscale magnetic structure of ferromagnet/antiferromagnet manganite multilayers
D. Niebieskikwiat, L. E. Hueso, J. A. Borchers +2
Polarized Neutron Reflectometry and magnetometry measurements have been used to obtain a comprehensive picture of the magnetic structure of a series of La{2/3}Sr{1/3}MnO{3}/Pr{2/3}…
Negative magnetocaloric effect from highly sensitive metamagnetism in CoMnSi_{1-x}Ge_{x}
K. G. Sandeman, R. Daou, S. Ozcan +3
We report a novel negative magnetocaloric effect in CoMnSi_{1-x}Ge_{x} arising from a metamagnetic magnetoelastic transition. The effect is of relevance to magnetic refrigeration o…
