Quantum spin ladder materials

Quantum spin ladder materials have attracted much recent interest (Takano 1996, Maekawa 1996). These materials consist of ladders made of AFM chains of 5 = 1/2 spins coupled by inter-chain AFM bonds. Examples of 2-leg ladder materials are SrCu203 and LaCuOis an example of a 3-leg ladder material is Sr2Cu205. Superconductivity has apparently been discovered in the ladder material Sro.4Ca13 6Cu24O41.84 under pressure with Tc 12K at 3 GPa (Uehara et al. 1996). Interest in quantum spin ladder materials is partly due to the fact that they are simple model systems for theories of superconductivity based on magnetic pairing mechanisms. [Pg.9]
