Orbital-order melting in rare-earth manganites: the role of super-exchange
Andreas Flesch, Guoren Zhang, Erik Koch +1
We study the mechanism of orbital-order melting observed at temperature T_OO in the series of rare-earth manganites. We find that many-body super-exchange yields a transition-tempe…

Ab initio study of the giant ferroelectric distortion and pressure induced spin-state transition in BiCoO3
Ting Jia, Hua Wu, Guoren Zhang +4
Using configuration-state-constrained electronic structure calculations based on the generalized gradient approximation plus Hubbard U method, we sought the origin of the giant tet…
