Novel magnetic arrangement and structural phase transition induced by spin-lattice coupling in multiferroics
Satadeep Bhattacharjee, Dovran Rahmedov, Dawei Wang +1
Using an effective Hamiltonian of mutiferroic BiFeO (BFO) as a toy model, we explore the effect of the coefficient, C, characterizing the strength of the spin-current interacti…

Terahertz dielectric response and coupled dynamics of ferroelectrics and multiferroics from effective Hamiltonian simulations
Dawei Wang, Jeevaka Weerasinghe, Abdullah Albarakati +1
Ferroelectric and multiferroic materials form an important class of functional materials. Over the last twenty years, first-principles-based effective Hamiltonian approaches have b…
