DOI: 10.1103/physrevb.99.064111
Abstract: We develop and/or use a combination of first-principles density functional theory and first-principles-based effective Hamiltonian approaches to investigate phase evolution in Ba(Ti1−x, Zrx )O3 ferroelectric relaxor. Our simulations reveal two competing effects, which are associated… read more here.
