Heavy rare earth Dysprosium has a complex magnetic structure, it is impossible to calculate directly its magnetization and magnetic entropy with Weiss 'molecular field theory. 重稀土Dy具有复杂的磁结构,不可能用外斯分子场理论直接计算它的磁化强度和磁熵。
Weiss's theory ( 1948) shows that the paramagnetic anisotropy does exist in the single crystals of chrome alums. Weiss理论(1948)为基础的计算表明铬矾单晶的顺磁各向异性是存在的。
Weiss's "molecular field" is the classical theory to explain self-magnetization, but the physical essence about "molecular field" is not explained by the Weiss's. 外斯(Weiss)“分子场”理论是解释自发磁化的经典理论,但并不能说明“分子场”的本质;
The axiomatic scheme of topological degree theory was given by Aman and Weiss in 1973. Space C ( X, X), which denotes a space of all continuous functions from Banach space X into X, has the topology of uniform convergence. 拓扑度理论的公理体系,已在1973年由Aman和Weiss给出,空间C(X,X)取一致收敛拓扑。
