TEMPERATURE BEHAVIOUR OF A "MAGNETIC" BAND IN NICKEL
The unoccupied Z(2)-d band in Ni(110) was studied as a function of temperature employing spin-resolved inverse photoemission. This band has only the majority spin states occupied at T=0 and contributes therefore to the ferromagnetism in nickel. As a function of temperature, the data show majority and minority features merging together upon approaching the Curie temperature T(c). This result indicates either a temperature-dependent exchange splitting vanishing at T(c) or (assuming a temperature-independent local exchange splitting) only a small amount of short-range magnetic order in nickel at T(c).
