摘要
Ground state of the mixed spin-(1,1/2) Ising-Heisenb erg distorted diamond chain in the presence of the external magnetic field is rigorously studied in the frustrated case of ferromagnetic Ising and antiferromagnetic XXZ Heisenberg interactions. The influence of quantum fluctuations, magnetic field, and the distortion of diamond cells on the ground state are examined in detail. It is established that the zero-temperature magnetization curve may show intermediate plateaus at zero and one-half of the saturation magnetization.
