Abstract
We present an accurate first-principles study of the spin-dependent plasma frequency of iron and cobalt using density-functional theory in an all-electron full-potential framework. The results are compared to the results obtained with standard pseudopotential approaches and experimental data obtained from photoemission, absorption, and electron energy loss spectra. Using our new implementation, we calculate plasma frequency for two spin channels separately. Our results explain the significant difference between observed contributions from majority and minority electrons to plasmon resonance in cobalt nanoparticles.
