14 Jul 1995 | | Subject: | cond-mat | | Affiliation: | MIT | | Abstract: | Quantum Heisenberg spin chains with random couplings and spin sizes are studied using a real-space renormalization group technique. These systems belong to a new universality class of disordered quantum spin systems realized in {it e.g.} ${
m Sr}_3{
m CuPt}_{1-x}{
m Ir}_x {
m O}_6$. The low-energy fixed point is characterized by the formation of weakly coupled large effective spins. At low temperature $T$ the entropy obeys a power law $T^delta$ ($deltaapprox0.44$), and the susceptibility follows a Curie-like behavior. | | Source: | arXiv, cond-mat/9507055 | | Other source: | [GID 358013] pmid10059870 | | Services: | Forum | Review | PDF | Favorites | |
