Propriétés magnétiques de l'état métallique et énergie d'interaction entre atomes magnétiques

Abstract: SOMMAIRE. -Une première partie du travail ( § 1 à 10) est consacrée à l'interprétation des expériences de M. Manders sur les variations, en fonction de la température, de la susceptibilité magnétique de quelques solutions solides à base de nickel (Ni et Al ou Ti, Sn, Sb, V, Mo, W, Cr). On étudie et on interprète les variations, en fonction du titre, de la constante de Curie et du coefficient de paramagnétisme constant superposé. Oo en déduit que les électrons magnétiques du nickel restent en nombre constant lo… Show more

“…When the exchange interaction between neighboring spins is of antiferromagnetic (AF) nature, two competing ground states capture the landscape of possibilities: a simple Néel-type long-range ordered (LRO) state described within the framework of classical mechanics [1] and a spin-singlet state formed by a superposition of spin states, which is a purely quantum mechanical concept [2].…”

“…1 There is no change in lines along microscopic spin directions between the state under a negative field and that under a positive field. As another origin of the jump, a spin-flop phenomenon [2][3][4] is widely known; the phenomenon is the occurrence of an abrupt change in lines along microscopic spin directions while the states change owing to the increase in magnetic field. We distinguish the type of magnetization jump in the ferromagnet and ferrimagnet mentioned above from the spin-flop phenomenon.…”

“…We probe the superexchange interactions by first preparing two atomic spin states of 87 Rb in an antiferromagnetic order (24) and then recording the time evolution of the spins of neighboring atoms in isolated double well potentials (25,26,27) for weak to strong tunnel couplings.…”
