Session L36 - General Poster Session II.
POSTER session, Wednesday morning, March 22
Exhibit Hall, MCC
A layer version of the tight-binding LMTO-GF method was used to obtain exchange interaction parameters and spin wave spectrum at the surface of elementary ferromagnets (Fe,Ni,Co) with the local spin-density functional approximation. Different ways of calculating of exchange parameters in density functional approach were used and the results compared. The stability and characteristic range of surface spin wavecompare to bulk ones have been estimated and possible connection with experimental data emphasized.
