Linear versus nonlinear electro-optic effects in materials
Zhijun Jiang, Charles Paillard, Hongjun Xiang +1
Two schemes are proposed to compute the nonlinear electro-optic (EO) tensor for the first time. In the first scheme, we compute the linear EO tensor of the structure under a finite…
Strain Control and Layer-Resolved Switching of Negative Capacitance in BaTiO/SrTiO Superlattices
Raymond Walter, Charles Paillard, Sergey Prosandeev +1
Negative capacitance in BaTiO/SrTiO superlattices is investigated by Monte Carlo simulations in an atomistic effective Hamiltonian model, using fluctuation formulas for res…
On the magnetoelastic and magnetoelectric couplings across the antiferromagnetic transition in multiferroic BiFeO3
Mariusz Lejman, Charles Paillard, Vincent Juvé +7
Clear anomalies in the lattice thermal expansion (deviation from linear variation) and elastic properties (softening of the sound velocity) at the antiferromagnetic-to-paramagnetic…
Strain and Magnetic Field Induced Spin-Structure Transitions in Multiferroic BiFeO3
A. Agbelele, D. Sando, C. Toulouse +17
The magnetic-field-dependent spin ordering of strained BiFeO3 films is determined using nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy t…
