Magnetoelectroelastic control of magnetism

Co magnetic moment as a function of applied electric field

X-ray magnetic circular dichroism at the Co L3,2 edges measured at the X-Treme beamline, SLS and at the Advanced Light Source, evidence that three distinct electric field driven remanent magnetization states can be set in the Co film at room temperature. Ab initio density functional theory calculations unravel the relative contributions of both strain and charge to the observed magnetic anisotropy changes illustrating magnetoelectroelastic coupling at artificial multiferroic interfaces.
