First principles electric field gradients at A and B site cations across the NaRTiO4 Ruddlesden Popper series
L. F. Almeida, A. N. Cesário, P. A. Sousa +5
The Ruddlesden-Popper titanates, NaRTiO (R = rare-earth), exhibit a structural behaviour where non-centrosymmetry is driven by cooperative oxygen octahedral rotations…
Self-thermometry measurements of the adiabatic temperature change in first-order phase transition magnetocaloric materials
Daniela O. Bastos, André M. R. Soares, Leonor Andrade +8
Accurately measuring the magnetocaloric effect is necessary to foster the development of magnetic refrigeration devices. However, current methods are inconvenient, requiring differ…
Rotating Magnetocaloric Effect in Sintered La(Fe,Mn,Si)H Plates
Rafael Almeida, Tomás Ventura, Ricardo Moura Costa Pinto +6
La-Fe-Si-based alloys are among the most application-ready magnetocaloric materials for room-temperature magnetic refrigeration. Powder metallurgy methods have been previously demo…
Rotating Magnetocaloric Effect in First-order Phase Transition Material Gd5Si2Ge2
Rafael Almeida, Rodrigo Kiefe, Ricardo Moura Costa Pinto +5
The rotating magnetocaloric effect (RMCE) induced by self-demagnetization has been investigated in the giant magnetocaloric effect (GMCE) material GdSiGe. This shape-de…
