摘要：

Using ultrahigh magnetic field up to 120 T, a 1/2 magnetization plateau within 11.7-34.8 T and a 3/4-like plateau within 55.6-87.0 T have been observed in the S-1 skew chain antiferromagnet Ni2V2O7. By combining density functional theory calculations, exact diagonalization, and quantum Monte Carlo simulations, we find that the nearest-neighbor interchain interaction (J3/kB = -78.5 K) is much stronger than the intrachain interactions (J1/kB = -1.0 K and J2/kB = 6.3 K), showing surprising "dimerization" of magnetic ions caused by the large 3d-orbital overlap along the Ni1-Ni1 bond. Thus a "dimer+monomer" model is proposed to describe the magnetization process-the 1/2 plateau pertains to weakly coupled Ni2 monomers while the 3/4-like plateau to the strongly coupled Ni1 dimers. The possible supersolid phases from the Ni1 dimers are proposed.
