| 中文摘要 | A tetragonal zircon-type DyCrO4 with space group I4(1)/amd was prepared at ambient pressure. By quenching this zircon phase from 6.0 GPa and 720 K, another tetragonal scheelite-type DyCrO4 was obtained with the reduction of lattice symmetry to I4(1)/a. Both phases contain spatially separated CrO4 tetrahedra with rare Cr5+ state and Cr-O-Dy-O-Cr spin interaction chains. In the zircon phase, significantly different Cr-O-Dy bond angles were found along different lattice axes, giving rise to ferromagnetic and antiferromagnetic interactions around 23 and 21 K, respectively. Due to magnetic frustration caused by the competitive ferromagnetic and antiferromagnetic interactions, a field-induced metamagnetic transition took place at a small field about 0.15 T. In the scheelite phase, antiferromagnetic ordering occurred below 24 K. Similar to the zircon phase, field-induced metamagnetism was also observed in the scheelite-type DyCrO4, but at a higher field of about 3.0 T. Possible orbital ordering was discussed in the high-pressure scheelite phase. |
