Spin Polarization of Low Energy Electrons Scattered from Magnetic Ni(110) Surfaces
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)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 ... -
Advantages to Be Gained from the Selective Spin-Wave Resonance Critical Angles Effect
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)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. -
Transition Radiation Emitted from a Surface Irregularity Shaped as Rectangular Step and Rectangular Groove
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)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. ... -
