Focusing effects for atoms sputtered from the (001) Ni face with energy and angular resolution

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.
