Magnetic properties of ternary compounds

  • Published:
Il Nuovo Cimento D

Summary

At present magnetism is becoming a more and more fundamental science. On the other hand, the solid-state chemists are able to prepare easily many new «magnetic» phases with a more or less complex crystal structure. There results a conflicting situation between the ideal expected models and the true behaviour of the real crystal. A strategy to tackle this important problem is suggested. Illustrations are given by analysing the properties of ternary compounds with different structural arrangements of their magnetic carriers such as chains or layers.

Riassunto

Oggi il magnetismo sta diventando una scienza sempre piú importante. D'altra parte, i chimici dello stato solido sono in grado di preparare facilmente molte nuove fasi magnetiche con struttura cristallina piú o meno complessa. Ne risulta una situazione conflittuale tra modelli ideali previsti e il vero comportamento dei cristalli reali. Si suggerisce una strategia per affrontare questo importante problema, illustrata analizzando le proprietà dei composti ternari con differenti sistemazioni strutturali dei loro portatori magnetici, come catene o strati.

Резюме

Магнетизм становится все более и более фундаментальной наукой. С другой стороны в химии твердого тела можно легко приготовить много новых «магнитных» фаз с более или менее сложной кристаллической структурой. Это приводит к конфликтной ситуации между идеальными моделями и истинным поведением реальных кристаллов. Проводится анализ свойствтрехкомпонентных соединений с различным структурным расположением магнитных носителей типа цепочек или слоев.
