A coupled magneto-structural continuum model for multiferroic
John Mangeri, Davi Rodrigues, Sudipta Biswas +3
A continuum approach to study magnetoelectric multiferroic (BFO) is proposed. Our modeling effort marries the ferroelectric (FE) phase field method and micromagn…
Giant voltage amplification from incipient ferroelectric states
Mónica Graf, Hugo Aramberri, Pavlo Zubko +1
Ferroelectrics subject to suitable electric boundary conditions present a steady negative capacitance response. When the ferroelectric is in a heterostructure, this behavior yields…
Coexisting conventional and inverse mechanocaloric effects in ferroelectrics
Diana E. Murillo-Navarro, Mónica Graf, Jorge Íñiguez
The mechanocaloric effect is the temperature change of a material upon application or removal of an external stress. Beyond its fundamental interest, this caloric response represen…
Perturbative approach to electrocaloric effects
Mónica Graf, Jorge Íñiguez
We show that the electrocaloric (EC) effect -- e.g., the temperature change experienced by an insulator upon application of an electric bias -- lends itself to a straightforward in…
Strain induced magnetic transition in CaMnO ultra thin films
A. López Pedroso, M. A. Barral, M. E. Graf +4
The effect of high tensile strain and low dimensionality on the magnetic and electronic properties of CaMnO ultrathin films, epitaxially grown on SrTiO substrates, are expe…
Phase Transitions and Antiferroelectrivity in BiFeO3 from Atomic Level Simulations
M. Graf, M. Sepliarsky, S. Tinte +1
The structural and polar properties of BiFeO3 at finite temperature are investigated using an atomistic shell model fitted to first-principles calculations. Molecular Dynamics simu…
