A Blume–Capel spin glass with competing crystal-field interactions on a hierarchical lattice

Snowman, Daniel P. - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 9, pp. 1505-1515

Renormalization-group methods are used with a hierarchical lattice to model a Blume–Capel spin glass with annealed vacancies and competing crystal-field interactions. The strength of competing cross-link interactions is progressively increased as the effects, upon the phase diagrams, are...
