Spin one Ising model with competing interactions on the Bethe lattice

Creators

Description

The phase diagram of the spin one Ising model with competing interactions between first and second nearest neighbors generations, single ion anisotropy and quadrupolar interactions is studied. Modulated phases, multiphase point and reentrances are observed and discussed. For high competing single ion anisotropy the paramagnetic phase reaches a finite region of the ground state. (author)

Abstract (Portuguese)

Estuda-se o diagrama de fases do modelo de Ising de um spin com competicao de interacoes entre geracoes dos primeiro e segundo vizinhos mais proximos, anisotropia de um ion, e interacoes quadrupolar. Fases moduladas, ponto multifase e re-entrancias sao observados e discutidos. Para alta competicao da anisotropia de um ion a fase paramagnetica alcanca uma regiao finita do estado fundamental.
