"electric currents generating magnetic fields reversing stored magnetization leads to energy loss to heat... use of electric fields rather than currents limited by assumption that electric field direction must align with magnetization reversal direction... overcome, with magnetization components perpendicular to electric field, reversible in multiferroic BiFe0.9Co0.1O3 single-crystal thin films grown in unconventional crystallographic orientation... field applied parallel to film surface induces perpendicular magnetization reversal"
