Résumé
A section through the three-dimensional Fermi surface of Ni has been mapped perpendicular to the [110] direction using angle-scanned photoemission. Regions of minority and majority spin bands, well separated in k space, can clearly be identified through comparison with a band structure calculation. The behavior of the different bands is observed for temperatures below and above the Curie temperature <i>T<sub>C</sub></i>. We find bands which move and bands which stay in place for going from <i>T</i><<i>T<sub>C</sub></i> to <i>T</i>><i>T<sub>C</sub></i>.
