Magnetic and structural anisotropies of Co2FeAl Heusler alloy epitaxial   thin films
  This paper shows the correlation between chemical order, lattice strains and magnetic properties of Heusler Co2FeAl films epitaxially grown on MgO(001). A detailed magnetic characterization has been performed using vector field magnetometery combined with numerical Stoner-Wohlfarth analysis. We demonstrate the presence of three types of in-plane anisotropies: one biaxial, as expected for the cubic symmetry, and other two uniaxial ones. The three anisotropies show different behavior with the annealing temperature. The biaxial anisotropy shows a monotonous increase. The uniaxial anisotropy, parallel with the hard biaxial axes, related to the chemical homogeneity, decreases, while the other, supposed to have magnetostatic origin, remains constant.
