摘要：

We performed first-principles relativistic full-potential linearized augmented plane-wave calculations for strained tetragonal ferromagnetic La(Ba)MnO3 with an assumed experimental structure of thin strained tetragonal La0.67Ca0.33MnO3 (LCMO) films grown on SrTiO3[001] and LaAlO3[001] substrates. The calculated uniaxial magnetic anisotropy energy (MAE) values are in good quantitative agreement with experiments for LCMO films on SrTiO3 substrate. We also analyze the applicability of linear magnetoelastic theory for describing the stain dependence of MAE, and estimate magnetostriction coefficient lambda(001). [S0163-1829(99)00234-9].
