Summary: | Phys. Rev. Lett. 121, 257201 (2018) Using high-resolution spin-resolved photoemission spectroscopy, we observed a
thermal spin depolarization to which all spin-polarized electrons contribute.
Furthermore we observed a distinct minority spin state near the Fermi level and
a corresponding depolarization that seldom contributes to demagnetization. The
origin of this depolarization has been identified as the many-body effect
characteristics of half-metallic ferromagnets. Our investigation opens an
experimental field of itinerant ferromagnetic physics focusing on phenomena
with sub-meV energy scale. |
