On the electron mechanism of suppression of the magnetic moment of nickel in its alloys with copper and zinc

Abstract

For the first time, the electronic structure of Ni, Cu, and Zn in Ni0.27Cu0.73, Ni0.18Cu0.51Zn0.31, and Cu0.66Zn0.34 and some other chemical compounds has been studied using the method of shifts of the K X-ray lines. Statistically reliable shifts (from the positions for the metal) of all diagram K-lines of Ni have been found for both alloys, whereas the shifts of the K-lines of Cu and Zn (also from the positions for the metals) are close to zero for all the alloys. For the first time, estimates have been obtained for the 3d- and/or 4s-facsimiles, i.e., shifts of all diagram lines caused by the removal of one 3d- and/or 4s-electrons. On the basis of these facsimiles, the found shifts of the K-lines of Ni in Ni0.27Cu0.73 and Ni0.18Cu0.51Zn0.31 have been explained by the transference of ≲0.10 and 0.15 of its 4s-electron to 3d-band of the same atom.
