TLDR
In this paper, the magnetization measurements on NiCr alloys were analyzed in terms of the itinerant band model of very weak ferromagnetism and several characteristic properties related to the effective exchange interaction and to the band structure near the Fermi level were deduced from this analysis.Abstract:
New magnetization measurements on NiCr alloys are reported. At increasing Cr concentrations c less than 11 at%, the mean atomic moment M0 = 0 for c = 12 at% Cr. In the critical concentration range, 11 < c < 15 at% Cr, the experimental data are analysed in terms of the itinerant band model of very weak ferromagnetism. Several characteristic properties related to the effective exchange interaction and to the band structure near the Fermi level are deduced from this analysis.
Des mesures d'aimantation d'alliages NiCr ont ete effectuees. Pour c<11% at., on observe une decroissance lineaire du moment magnetique par atome moyen M0 = 0,616 μB – 0,051 c μB. Cette partie lineaire s'extrapole a zero pour c = 12% at. Cr. Les resultats obtenus dans la region critique de disparition du ferromagnetisme, 11 < c <15% at. Cr. ont ete analyses dans un modele d'electron collectif applique au cas du ferromagnetisme tres faible. On en deduit plusieurs proprietes caracteristiques en rapport avec l'interaction d'echange effective et la densite d'etat au niveau de Fermi.read more

Le champ moléculaire du nickel
TL;DR: In this article, it was shown that the magnetic field of the metal ferromagnetique is not proportional to the magnetization of the ferromagnetic metal because there appear corrective terms in M3, M5, and M6.
