Impurities in Quasi One-Dimensional Systems. A Study on Some Thermodynamic Properties

摘要

The effect of impurity in a magnetic system depends on the character of the impurity (magnetic or nonmagnetic) as well as on the dimensionality of the system. Amorphous and random magnetic systems are defined and the theoretical methods used to compute the behavior of quasi-one dimensional mixed magnetic systems with anisotropic interactions are presented. Various Mn (++) systems mixed with Cu or Cd are described. As well as the magnetic properties of the quasis one dimensional system (CH3)2NH2MnCl3. Quasi one dimensional systems Co(++) systems, mixed with Cu are discussed as well as the mixed CsMn (Cl sub(1-x) Br sub x)3 H2O.
