Exchange stiffness constant of two-dimensional Ni (100), (110) and (111) orientations

The exchange stiffness constant D of unsupported fcc (100), (110) and (111) nickel monolayers are calculated. It is shown that D is highly anisotropic for the (110) orientation. The relation between the strength of the magnetic coupling in the ground-state and the electronic structure of the monolay...

Description
Summary:The exchange stiffness constant D of unsupported fcc (100), (110) and (111) nickel monolayers are calculated. It is shown that D is highly anisotropic for the (110) orientation. The relation between the strength of the magnetic coupling in the ground-state and the electronic structure of the monolayers is pointed out.
