Fluctuating local magnetic moments in ferromagnetic Ni observed by the spin-resolved resonant photoemission

Abstract

We have measured the spin- and angle-resolved resonant photoemission spectra of ferromagnetic Ni(110) near the 3p threshold in the temperature range from T/${\mathit{T}}_{\mathit{C}}$=0.5 to 1.05. The spin polarization of the 6 eV satellite decreases with increasing temperature. The photon energy dependence of the spin polarization of the 6 eV satellite shows a dip profile near the 3p threshold, while its spectra feature remians unaltered at elevated temperature. These results indicate the evidence of the fluctuating local magnetic moments in ferromagnetic Ni.
