A new spinwave expansion for the ordered Kondo lattice
Nic Shannon
Abstract
We present a concise introduction to a new spinwave expansion scheme for magnetically ordered Kondo lattice models. This is motivated by consideration of the ferromagnetically ordered phase of the "double exchange" system La(1-x)Ca(x)MnO3. A brief overview is given of the consequences of quantum and thermal fluctuation effects for the magnetic properties of the double exchange ferromagnet.
