Abstract
The magnetocrystalline anisotropy energy of NiFe2O4 under uniaxial strain along [0 0 1] direction has been studied by using the linear muffin-tin orbital method within the density functional theory. The calculated uniaxial anisotropy constant Kout is positive for extensive in-plane strains and is negative for compressive in-plane strains. The large value of positive Kout indicates that a NiFe2O4 film under an extensive in-plane strain would strongly prefer the out-of-plane magnetization. © 2002 Elsevier Science B.V.
