Electric field dependence of the giant magnetic anisotropy of Ru monolayer on MgO(001) substrate
Source abstract
Abstract
Magnetic anisotropy energy (MAE) of a Ru monolayer on MgO(001) substrate under the application of an electric field is investigated by using first-principles calculations. Owing to the large spin orbit coupling in Ru atoms, both MAE and its rate of change against electric field are about 3 times as large as those of an Fe monolayer on MgO(001) substrate. The change rate of MAE of Ru/MgO has an opposite sign to that of Fe/MgO, which originates from the modification of the band structure near the Fermi energy around Γ¯ point caused by the application of an electric field.
