Magnetization plateaus in a solvable 3-leg spin ladder
We present a solvable ladder model which displays magnetization plateaus at fractional values of the total magnetization. Plateau signatures are also shown to exist along special lines. The model has isotropic Heisenberg interactions with additional many-body terms. The phase diagram can be calculated exactly for all values of the rung coupling and the magnetic field. We also derive the anomalous behavior of the susceptibility near the plateau boundaries. There is good agreement with the phase...[Show more]
