โœฆ Synopsis

We study the effect of spin fluctuations in antiferromagnetic alloys described by the generalized Rice model, by using the renormalized spin-fluctuation theory combined with the coherent-potential approximation. It is shown that the property of spin fluctuations is significantly modified by the presence of impurities and that the effect of spin fluctuations becomes considerable in dirty antiferromagnets near the critical concentration, above which antiferromagnetism disappears.

The effect of spin fluctuations in antiferromagnetic metals described by a nesting-type model is studied for paramagnetic states and for commensurate spin-density-wave states by the application of the renormalized spin fluctuation theory to the Rice model as well as to the Shibatani-Motizuki-Nagamiy
