Magnetization curves for quasi-periodic AFM Heisenberg chains.

Magnetization versus h for systems with λ = 0.8, δ = 0 and different chain lengths under PBC. From left to right, (a) , (b) , (c) . L = 50, 100 and 200 are represented by solid (green), dashed dotted (blue) and dashed (red) lines, respectively. The horizontal dashed (black) lines denote the specific α-dependent values discussed in the main text.
