Stachulec, Kazimierz
The continuation of an analytical approach to elastic spin polarized low energy electron
diffraction (SPLEED) [1] from magnetic surfaces is presented and searched numerically using three
different layer dependent surface magnetization models of the Ni(l10) surfaces case. In the approach,
the dynamical surface scattering LEED and exchange potentials are expressed in terms of the effective
scattering potentials of a free atom. The SPLEED exchange scattering asymmetry during the reversal
of the polarization direction of the incident electron beam are given in analytical form and the
asymmetry effects are computed numerically. The temperature dependence of the surface polarization
effect for nickel surfaces is presented graphically. The obtained results correspond to those of
experiments and literature.

We show that the exchange constant and surface anisotropy constants of a thin
ferromagnetic film can be determined by measuring the critical angles at which the successive
spin-wave mode peaks vanish.

Rutkowski, Jerzy H.
Transition radiation emitted when a nonrelativistic particle (β=0.2-0.5) enters a surface
irregularity shaped as a rectangular step and a rectangular groove and having the dielectric constant
ε=1.4-3.8 has been investigated. The angular distribution of the radiation intensity as well as its
dependence on the height of the irregularities, the width of the groove and the distance between the
irregularity edge and the entry point of the particle have been calculated on the basis of the theory of
Bagiyan and Ter-Mikaelyan.
