▲ [11a-S302-2] Higher order magnetic anisotropy in Fe/MgO under electric field: a first-principles calculations

〇Yukie Kitaoka¹, Hiroshi Imamura¹ (1.AIST)

Keywords:magnetic anisotropy, first-principles calculations, electric field

We study the first- and the second-order magnetic anisotropy coefficients, K₁ and K₂, in Fe thin films on MgO substrates under electric fields by using first-principles calculations. The electric field derivatives of K₁ and K₂have the opposite sign to each other as observed in recent experiments.
