Abstract

An anisotropic cubic ferromagnetic is investigated using the theory proposed by the present author in earlier papers. The cases of pseudodipolar coupling and of spin quantum number S = 1/2 are considered. The free energy of a ferromagnetic is derived in the form of an infinite convergent series of connected ladder diagrams. The accuracy of this method is restricted to terms proportional to the power 3/2 of the quotient of the absolute and Curie temperatures and to the square of the pseudodipolar coupling constant. Kinematic interaction is shown to be negligible to the accuracy adopted.

## Abstract Kinematical corrections derived in Part I are estimated to yield contributions smaller than (__T__/__T__~__c__~)^4^ to the statistical function at low temperatures (__T__ being the absolute and __T__~__c__~ the Curie temperature). It is proved that the kinematical corrections for an iso
