Experimental band structure and temperature-Dependent magnetic exchange splitting of nickel using angle-Resolved photoemission
Abstract
Using angle-resolved photoemission and synchrotron radiation, we have determined the energy-versus-momentum valence-band dispersion relations for a Ni(111) crystal. The temperature-dependent ferromagnetic exchange splitting has been directly observed. Both the d-band width (∼3.4 eV at L) and exchange splitting (0.31 eV) are much smaller than theoretical estimates (∼4.5 eV wide at L with ∼0.7-eV splitting, respectively, at 293 K). © 1978 The American Physical Society.
