Infinite series of magnetization plateaus in the frustrated dimer-plaquette chain

arXiv:cond-mat/0107137 · doi:10.1103/PhysRevB.65.054420

Abstract

The dimer-plaquette chain undergoes a first order transition driven by frustration to an orthogonal dimer ground state. We analyze the magnetization curve in this orthogonal dimer regime. Besides of the recently found magnetization plateaus at m=1/4 and the m=1/2 we find an infinite sequence of plateaus between m=1/4 and m=1/2. These additional plateaus belong to magnetizations m(n)=n/(2n+2), where n is a positive integer number.
