The Magnetic Susceptibility and Constitution of Coloured Glasses -
Part I. Theoretical Considerations and Experimental Method

JSGT 1951 V35 T005-T024

A somewhat detailed discussion is given of the magnetic properties of matter, with particular reference to the paramagnetic susceptibility of transition and rare-earth elements and ions. It is concluded on the basis of published work on the magnetic properties and colour of complexes that there is no reasonable doubt that an important relationship can be deduced between the magnetic properties and the type of bond of the colouring ions in glass. Previous work on glasses is briefly summarised. It is shown that the co-ordination number theory and the covalency concept are fundamentally similar, but that the former cannot be related to magnetic properties. Details are given of the method used for the determination of the susceptibility of glass and for the calculation of the magnetic moment exhibited by the element concerned.
