摘要：

The temperature dependence of the valence-band energy-distribution curves of ultrathin Fe/W(100) films has been measured with use of spin- and angle-resolved photoemission. Majority and minority features at GAMMA-BAR are stationary with increasing temperature; apparent peak broadening is caused by the emergence of "extraordinary" peaks. Comparison with a cluster calculation suggests that short-range ferromagnetic order approximately 4 angstrom exists above T(C) in the 1.5-monolayer film.
