چکیده انگلیسی
The magnetism of Ni(1Â 1Â 0) and Fe(1Â 1Â 0) surfaces was investigated by electron capture spectroscopy. He+ and He2+ ions impinged on the Fe(1Â 1Â 0) and Ni(1Â 1Â 0) surfaces under grazing incidence, and the degree of polarization of the light emitted by the neutralized projectiles was analyzed. Our measurements show that in Ni(1Â 1Â 0) minority electrons have a higher density of states at the Fermi energy than majority electrons, opposed to the Fe(1Â 1Â 0) case. From a comparison of our measurements we estimate the ratio between captured minority and majority electrons in Ni(1Â 1Â 0) to be similar as the ratio between captured majority and minority electrons in Fe(1Â 1Â 0).
