摘要：
We study the spin-3/2 Hubbard-Kondo lattice model by means of the Composite Operator Method, after applying a Holstein-Primakov transformation. The spin and particle dynamics in the ferromagnetic state are calculated by taking into account strong on-site correlations between electrons and antiferromagnetic exchange among 3/2 spins, together with usual Hund coupling between electrons and spins.
