Interplay of magnetism and valence instabilities in lanthanide systems
The valence instability in lanthanide systems is described within an extended periodic Anderson Hamiltonian (EPAM) which includes Coulomb repulsion between f- and conduction- electrons, allowing to describe both discontinuous and continuous valence variations. We investigate the connection be-tween...

| الملخص: | The valence instability in lanthanide systems is described within an extended periodic Anderson Hamiltonian (EPAM) which includes Coulomb repulsion between f- and conduction- electrons, allowing to describe both discontinuous and continuous valence variations. We investigate the connection be-tween valence and magnetism in this model and show that it can be applied to several lanthanide compounds showing both magnetic and valence instabilities. |
