Abstract
A simple new approach to the spin fluctuation problem is presented. Its basis is that the fluctuating moments may themselves be expressed in terms of the bulk magnetisation. On this basis magnetic and magnetoeleastic properties are calculated. The Curie temperatures obtained for a wide variety of materials agree well with experiment.
