| 英文摘要 | We perform a comparative magnetic study on two series of rare-earth (RE) based double perovskite iridates RE2BIrO6(RE = Pr, Nd, Sm-Gd; B = Zn, Mg), which show Mott insulating state with tunable charge energy gap from similar to 330 meV to similar to 560 meV by changing RE cations. For nonmagnetic RE = Eu cations, Eu(2)MgIrO(6)shows antiferromagnetic (AFM) order and field-induced spin-flop transitions below Neel temperature (T-N) in comparison with the ferromagnetic (FM)-like behaviors of Eu(2)ZnIrO(6)at low temperatures. For magnetic-moment-containing RE ions, Gd(2)BIrO(6)show contrasting magnetic behaviors with FM-like transition (B = Zn) and AFM order (B = Mg), respectively. While, for RE = Pr, Nd and Sm ions, all members show AFM ground state and field-induced spin-flop transitions belowT(N)irrespective of B = Zn or Mg cations. Moreover, two successive field-induced metamagnetic transitions are observed for RE2ZnIrO6(RE = Pr, Nd) in high field up to 56 T, the resultant field temperature (H-T) phase diagrams are constructed. The diverse magnetic behaviors in RE(2)BIrO(6)reveal that the 4f-Ir exchange interactions between the RE and Ir sublattices can mediate their magnetism. |
