  Peculiarities of the focusing and overfocusing of atoms sputtered from the
surface of (001) Ni face are studied with the use of molecular dynamics
computer simulations. It is discovered that the numbers of focused and
overfocused sputtered atoms decrease under the transition of the (001) Ni face
from the paramagnetic to the ferromagnetic state. The evolution of the
two-dimensional energy and polar angle resolved distributions of sputtered
atoms when changing the azimuthal angle and the binding energy of atoms at the
surface is investigated.
