We study the frustrated dimer-plaquette quantum spin chain for ferromagneticdimer bonds. This quantum system undergoes a series of first-order ground-statephase transitions driven by frustration or by a magnetic field. We find thatthe different nature of the ground-state phases has a strong influence on themagnetization curve as well as the low-temperature thermodynamics. Inparticular, the magnetization curve exhibits plateaus and jumps, the number ofwhich depends on the strength of frustration. The temperature dependence of thesusceptibility may either show activated spin-gap behaviour for smallfrustration or Curie like paramagnetic behaviour for strong frustration.Comment: 14 pages, 11 figures, submitted to Phys. Rev.
