- Descrição
- The magnetic behavior at T = 0 K of a system consisting of conduction electrons coupled to localized electrons (e.g. 4f electrons), the latter submitted to an inhomogeneous crystal field distribution, is studied. We consider a simple crystal field distribution and define an average ionic magnetic moment using the results of the homogeneous case. We obtain a condition for the onset of spontaneous magnetic order and study the magnetic behavior in the paramagnetic and ferromagnetic regions of the phase diagram. The study implies that the inhomogeneity of the crystal field attenuates the quenching effects. The model is interesting to the study of disordered rare-earth intermetallic compounds.
